40 Answer: d

Explanation: ^ is the Binary XOR operator.

41 Answer: a

Explanation: Although the presence of parenthesis does affect the order of precedence, in the case shown above, it is not making a difference. The result of both of these expressions is 1.333333333. Hence the statement is true.

42 Answer: b Explanation: The order of precedence is: %, +. Hence the expression above, on simplification results in 4 + 3 = 7. Hence the result is 7.

43 Answer: b



Explanation: The above expression is evaluated as: 16%15//16, which is equal to 1//16, which results in 0.

44 Answer: d

Explanation: All of the operators shown above have associativity from left to right, except exponentiation operator (**) which has its associativity from right to left.

45 Answer: b

Explanation: The expression shown above is an example of explicit conversion. It is evaluated as int(43.55+1) = int(44.55) = 44. Hence the result of this expression is 44.

46 Answer: b

Explanation: The result of the expression shown above is 1.0 because print rounds off digits.

47 Answer: d

Explanation: The expression shown above is evaluated as: 2+9*(36-8)/10, which simplifies to give 2+9*(2.8), which is equal to 2+25.2 = 27.2. Hence the result of this expression is 27.2.

48 Answer: c Explanation: Coercion is the implicit (automatic) conversion of operands to a common type. Coercion is automatically performed on mixed-type expressions. The expression 1.7 % 2 is evaluated as 1.7 % 2.0 (that is, automatic conversion of int to float).

49 Answer: a

Explanation: The expressions are evaluated as: 4%3 and 6//2 respectively. This results in the answer (1,3). This is because the associativity of both of the expressions shown above is left to right.

50 Answer: b

Explanation: The highest precedence is that of the exponentiation operator, that is of **.

51 Answer: d

Explanation: The binary form of 1 is 0001. The expression x<<2 implies we are performing bitwise left shift on x. This shift yields the value: 0100, which is the binary form of the number 4.

52 Answer: b Explanation: The binary form of the number 29 is 11101. Hence the output of this expression is ‘0b11101’.

53 Answer: a

Explanation: When the value of x is equal to 8 (1000), then x>>2 (bitwise right shift) yields the value 0010, which is equal to 2. Hence the value of x is 8.

54 Answer: a

Explanation: The result of the expression shown will be 1011. This is because we have not specified the base in this expression. Hence it automatically takes the base as 10.

55 Answer: d

Explanation: The expression int(‘1111’,2) gives the result 15. The expression int(‘1111’, 10) will give the result 1111.

56 Answer: b

Explanation: In most cases the value of two’s complement is different from the original



value. However, there are cases in which the two’s complement value may be equal to the original value. For example, the two’s complement of 10000000 is also equal to 10000000. Hence the statement is false.

57 Answer: a

Explanation: The one’s complement of a value is obtained by simply changing all the 1’s to 0’s and all the 0’s to 1’s. Hence the one’s complement of 110010101 is 001101010.

58 Answer: c

Explanation: Bitwise XOR gives 1 if either of the bits is 1 and 0 when both of the bits are 1.

59 Answer: c

Explanation: ^ is the XOR operator. The binary form of 4 is 0100 and that of 12 is 1100. Therefore, 0100^1100 is 1000, which is equal to 8.

60 Answer: c

Explanation: Any odd number on being AND-ed with 1 always gives 1. Any even number on being AND-ed with this value always gives 0.

61 Answer: d Explanation: The Boolean function returns true if the argument passed to the bool function does not amount to zero. In the first example, the string ‘False’ is passed to the function bool. This does not amount to zero and hence the output is true. In the second function, an empty list is passed to the function bool. Hence the output is false.

62 Answer: c

Explanation: The line of code shown above can be simplified to state that ‘hello’ should be printed if the argument passed to the Boolean function amounts to zero, else ‘morning’ will be printed.

63 Answer: b

Explanation: The function not returns true if the argument amounts to false, and false if the argument amounts to true. Hence the first function returns false, and the second function returns false.

64 Answer: a

Explanation: The line of code can be translated to state that ‘f’ is printed if the argument passed to the Boolean function amount to zero. Else ‘t’ is printed. The argument given to the Boolean function in the above case is ‘spam’, which does not amount to zero. Hence the output is: t.

65 Answer: d

Explanation: The code shown above returns a new list containing only those elements of the list l which do not amount to zero. Hence the output is: *1, 2, ‘hello’+

66 Answer: d

Explanation: The code snippet shown above results in an error because the above formatting option works only if ‘X’ is a number. Since in the above case ‘X’ is a string, an error is thrown.

67 Answer: a

Explanation: The formatting option print(“%Ns”,X) helps us add ‘N’ number of spaces before a given string ‘X’. Hence the output for the code snippet shown above will be 56 blank spaces before the string “san-foundry”.



68 Answer: c

Explanation: The expression shown above results in the output 456.

69 Answer: b

Explanation: The above expression returns the output 000345. It adds the required number of zeroes before the given number in order to make the number of digits 6 (as specified in this case).

70 Answer: d

Explanation: In order to add ‘n’ blank spaces after a given string ‘S’, we use the formatting option:(“%-ns”%S).

71 Answer: c

Explanation: In the snippet of code shown above, three values are inserted into the target string. When we insert more than one value, we should group the values on the right in a tuple. The % formatting expression operator expects either a single item or a tuple of one or more items on its right side.

72 Answer: b Explanation: The code ‘There are %d %s birds.’ %(4, blue) results in the output: There are 4 blue birds. When we insert more than one value, we should group the values on the right in a tuple.

73 Answer: a

Explanation: The code shown above prints 1234 for the format specified %d, ‘ 1234’ for the format specifier %-6d, and 001234 for the format specifier %06d. Hence the output of this code is: ) ‘integers:…1234…1234 …001234’

74 Answer: d

Explanation: The %f %e and %g format specifiers represent floating point numbers in different ways. %e and %E are the same, except that the exponent is in lowercase. %g chooses the format by number content. Hence the output of this code is: ‘3.345679 | 3.345679e+00 | 3.34568’.

75 Answer: a

Explanation: The code shown above rounds the floating point value to two decimal places. In this code, a variety of addition formatting features such as zero padding, total field width etc. Hence the output of this code is: ‘3.35 | 03.35 | +003.3’.

76 Answer: a

Explanation: In the code shown above, the value for first is substituted by l[0], that is H and the value for third is substituted by l[2], that is L. Hence the output of the code shown above is: ‘first=H, third=L’. The list l= *‘H’, ‘E’, ‘L’, ‘L’, ‘O’+.

Explanation: In the code shown above, the value for a is substituted by l*0+, that is ‘H’, the value of b is substituted by l[-1+, that is ‘O’ and the value for c is substituted by l*1:3+. Here the use of *p is to unpack a tuple items into individual function arguments.

78 Answer: b

Explanation: The formatting method {1:<10} represents the second positional argument, left justified in a 10 character wide field.

79 Answer: d

77 Answer: c



Explanation: The code shown above converts the value 255 into hexadecimal, that is, 0xff. The value ‘FF’ into integer. Hence the output of the code shown is: (‘0xff’, 255, 255).

Explanation: The output of both of the codes shown above is ‘0b1111111111111111’. Hence the statement is true.

81 Answer: d

Explanation: The code shown above first prints the word “Decorated” and then “ordinary”. Hence the output of this code is:

82 Answer: b

Explanation: In the code shown above, the function mk() is the decorator. The function which is getting decorated is mk2(). The return function is given the name p().

83 Answer: c

Explanation: The @ symbol along with the name of the decorator function can be placed above the definition of the function to be decorated works as an alternate way for decorating a function.

84 Answer: a Explanation: The code shown above returns the address on the function ordi first, after which the word “Ordinary” is printed. Hence the output of this code is:

Address

Ordinary.

85 Answer: a

Explanation: The @ symbol can be used as an alternate way to specify a function that needs to be decorated. The output of the codes shown above is the same. Hence they are equivalent. Therefore this statement is true.

86 Answer: a

Explanation: The function upper() does not modify a string in place, it returns a new string which isn’t being stored anywhere.

87 Answer: d

Explanation: The loop does not terminate as new elements are being added to the list in each iteration.

88 Answer: c

Explanation: SyntaxError, there shouldn’t be a space between + and = in +=.

89 Answer: a

99 Answer: c

Explanation: Max returns the maximum element in the list.

100 Answer: d

Explanation: Min returns the minimum element in the list.

101 Answer: b

Explanation: In matrix B will result in an error because in the absence of a comma at the end of each row, it behaves like three separate lists. The error thrown states that the list integers must be integers or slices, not tuples.

102 Answer: a

Explanation: We can index the rows and columns using normal index operations. The statement A[1] represents the second row, that is, the middle row. Hence the output of the code will be: [4, 5, 6].

103 Answer: c

Explanation: The output that is required is 6, that is, row 2, item 3. This position is represented by the statement: A[1][2].

104 Answer: c Explanation: To get a particular column as output, we can simple iterate across the rows and pull out the desired column, or iterate through positions in rows and index as we go. Hence the output of the code shown above is: [2, 5, 8].

105 Answer: a

Explanation: We can also perform tasks like pulling out a diagonal. The expression shown above uses range to generate the list of offsets and the indices with the row and column the same, picking out A[0][0], then A[1][1] and so on. Hence the output of the code is: [1, 5, 9].

106 Answer: d

Explanation: The function seed is a function which is present in the random module. The functions sqrt and factorial are a part of the math module. The print function is a built-in function which prints a value directly to the system output.

107 Answer: b

Explanation: This is a built-in function which rounds a number to give precision in decimal digits. In the above case, since the number of decimal places has not been specified, the decimal number is rounded off to a whole number. Hence the output will be 5.

108 Answer: c



Explanation: The built-in function pow() can accept two or three arguments. When it takes in two arguments, they are evaluated as: x**y. When it takes in three arguments, they are evaluated as: (x**y)%z.

109 Answer: c

Explanation: The function all returns false if any one of the elements of the iterable is zero and true if all the elements of the iterable are non zero. Hence the output of this function will be false.

110 Answer: c

Explanation: The function round is used to round off the given decimal number to the specified decimal places. In this case the number should be rounded off to two decimal places. Hence the output will be 4.57.

111 Answer: a

Explanation: Functions are reusable pieces of programs. They allow you to give a name to a block of statements, allowing you to run that block using the specified name anywhere in your program and any number of times.

112 Answer: c

Explanation: None.

113 Answer: a

Explanation: Functions are defined using the def keyword. After this keyword comes an identifier name for the function, followed by a pair of parentheses which may enclose some names of variables, and by the final colon that ends the line. Next follows the block of statements that are part of this function.

defsayHello():

print('Hello World!') # block belonging to the function

# End of function #

sayHello() # call the function

sayHello() # call the function again

114 Answer: c Explanation: Here, we define a function called printMax that uses two parameters called a and b. We find out the greater number using a simple if..else statement and then print the bigger number.

115 Answer: a

Explanation: The first time that we print the value of the name x with the first line in the function’s body, Python uses the value of the parameter declared in the main block, above the function definition. Next, we assign the value 2 to x. The name x is local to our function. So, when we change the value of x in the function, the x defined in the main block remains unaffected. With the last print function call, we display the value of x as defined in the main block, thereby confirming that it is actually unaffected by the local assignment within the previously called function.

116 Answer: c

Explanation: In the code shown above, x=15 is a local variable whereas x=12 is a global variable. Preference is given to local variable over global variable. Hence the output of the



code shown above is 15.

117 Answer: b

Explanation: The variable x is a local variable. It is first printed and then modified. Hence the output of this code is 100.

118 Answer: a Explanation: The value passed to the function san() is 12. This value is incremented by one and printed. Hence the output of the code shown above is 13.

119 Answer: d

Explanation: In the code shown above, the variable ‘x’ is declared as global within the function. Hence the output is ‘x’. Had the variable ‘x’ been a local variable, the output would have been:

13

x

120 Answer: a

Explanation: The code shown above will result in an error because ‘x’ is a global variable. Had it been a local variable, the output would be: 16

hello

121 Answer: d

Explanation: Both str(f) and format(f) call f. str ().

122 Answer: c

Explanation: lt overloads the < operator>.

123 Answer: a

Explanation: Refer documentation.

124 Answer: b

Explanation: invert () overloads ~.

125 Answer: a

Explanation: The other two do not exist.

126 Answer: b

Explanation: An object represents an entity in the real world that can be distinctly identified. A class may define an object.

127 Answer: b

Explanation: The values assigned by the constructor to the class members is used to create the object.

128 Answer: c

Explanation: The program has no error. “Hello World” is displayed. Execute in python shell to verify.

129 Answer: b

Explanation: setattr(obj,name,value) is used to set an attribute. If attribute doesn’t exist, then it would be created.

130 Answer: a

Explanation: getattr(obj,name) is used to get the attribute of an object.

131 Answer: a



Explanation: If the class definition is class B(A): then class B inherits the methods of class A. This is called inheritance.

132 Answer: c

Explanation: Any changes made to the private members of the class in the subclass aren’t reflected in the original members.

133 Answer: b

Explanation: Since the object for the derived class is declared first, new () method of the derived class is invoked first, followed by the constructor and the new () method of main class.

134 Answer: c

Explanation: Since the invoking method, Test. init (self), isn’t present in the derived class, variable x can’t be inherited.

135 Answer: d

Explanation: Class B inherits class A hence the function disp () becomes part of class B’s definition. Hence disp() method is properly executed and the line is printed.

136 Answer: d Explanation: Polymorphism is a feature of object-oriented programming languages. It allows for the implementation of elegant software that is well designed and easily modified.

137 Answer: c

Explanation: Polymorphism allows for the implementation of elegant software.

138 Answer: c Explanation: In Python, any set of classes with a common set of methods can be treated similarly. This is called duck typing. Hence duck typing imposes less restrictions.

139 Answer: a

Explanation: The super(). init () in the subclasses has been properly invoked and none of other subclasses return any other value. Hence 1 is returned each time the object is created and printed.

140 Answer: d

Explanation: The derived class method change() overrides the base class method.

141 Answer: c

Explanation: Instantiation simply refers to creation of an instance of class. It is not a fundamental feature of OOP.

142 Answer: b

Explanation: The values assigned by the constructor to the class members is used to create the object.

143 Answer: c Explanation: The program has no error because the class member which is public is printed. 1 is displayed. Execute in python shell to verify.

144 Answer: c

Explanation: Variables beginning with two underscores are said to be private members of the class and they can’t be accessed directly.

145 Answer: a



Explanation: The purpose of getters and setters is to get(return) and set(assign) private instance variables of a class.

146 Answer: d

Explanation: There has to be at least one except statement.

147 Answer: c

Explanation: The else part is executed when no exception occurs.

148 Answer: b


149 Answer: d


150 Answer: a

Explanation: Each type of exception can be specified directly. There is no need to put it in a list.
