Question 1

What is the output of the following code :
Print 9//2
A)4.5
B)4.0
C)4
D)Error

Accepted Answer

The // operator in Python performs floor division, which means it divides the number and rounds down to the nearest integer. Therefore, 9//2 equals 4.

Question 2

Which function overloads the >> operator?
A)more()
B)gt()
C)ge()
D)rshift()

Accepted Answer

The `rshift()` function overloads the `>>` operator in Python, allowing for the implementation of custom behavior when the right shift operation is used on instances of a class.

Question 3

What is the output of the following program :
I = 0
While i < 3:
Print i
Print i+1
A)0 2 1 3 2 4
B)0 1 2 3 4 5
C)0 1 1 2 2 3
D)1 0 2 4 3 5

Accepted Answer

The program contains a syntax error due to the capitalization of "While" and "Print", which should be lowercase ("while" and "print") in Python. However, if corrected, the loop would print each value of 'i' followed by 'i+1' for each iteration, starting from 0 until 'i' is less than 3, resulting in the sequence 0 1 1 2 2 3.

Question 4

Which module in Python supports regular expressions?
A)re
B)regex
C)pyregex
D)None of the above

Accepted Answer

The "re" module in Python provides support for working with regular expressions.

Question 5

What is the output of the following program :
Print 0.1 + 0.2 == 0.3
A)True
B)False
C)Machine dependent
D)Error

Accepted Answer

Due to the way floating-point arithmetic is handled in computers, the sum of 0.1 and 0.2 does not exactly equal 0.3, leading to the output being False.

Question 6

Which of these is not a core data type?
A)Lists
B)Dictionary
C)Tuples
D)Class

Accepted Answer

Class is not considered a core data type in Python. Core data types include Lists, Dictionaries, and Tuples, which are built into the language and provide the basic means of storing and manipulating data. Classes, on the other hand, are used for object-oriented programming to create user-defined data structures.

Question 7

What data type is the object below?
L = [1, 23, „hello?, 1]
A)List
B)Dictionary
C)Tuple
D)Array

Accepted Answer

The object is a list, denoted by square brackets []. Lists can contain elements of different types, as shown in the example.

Question 8

What is the output of the following program :
Def myfunc(a):
A = a + 2
A = a * 2
Return a
Print myfunc(2)
A)8
B)16
C)Indentation Error
D)Runtime Error

Accepted Answer

The code snippet provided has incorrect indentation, which is crucial in Python for defining the scope of functions, loops, and conditionals. Python relies on indentation to define the blocks of code.

Question 9

What is the output of the expression : 3*1**3
A)27
B)9
C)3
D)1

Accepted Answer

The expression follows the order of operations: exponentiation before multiplication. Thus, 1**3 equals 1, and 3*1 equals 3.

Question 10

What is the output of the following program :
Print '{0:.2}'.format(1.0 / 3)
A)0.333333
B)0.33
C)0.333333:-2
D)Error

Accepted Answer

The format specifier '{0:.2}' tells Python to format the first argument (1.0 / 3) with 2 significant digits, resulting in '0.33'.

Question 11

What is the output of the following program :
Print '{0:-2%}'.format(1.0 / 3)
A)0.33
B)0.33%
C)33.33%
D)33%

Accepted Answer

The format specifier '{0:-2%}' formats the number 1.0 / 3 (which is approximately 0.3333) as a percentage with two decimal places, resulting in '33.33%'.

Question 12

What is the output of the following program :
I = 0
While i < 3:
Print I
I += 1
Else:
Print 0
A)0 1 2 3 0
B)0 1 2 0
C)0 1 2
D)Error

Accepted Answer

The answer of What is the output of the following...

Question 13

What is the output of the following program :
I = 0
While i < 5:
Print(i)
I += 1
If i == 3:
Break
Else:
Print(0)
A)0 1 2 0
B)0 1 2
C)Error
D)None of the above

Accepted Answer

The answer of What is the output of the following...

Question 14

What is the output of the following program :
Print 'cd'.partition('cd')
A)(„cd?)
B)(")
C)(„cd?, ", ")
D)(", „cd?, ")

Accepted Answer

The `partition` method in Python splits the string at the first occurrence of the specified separator and returns a tuple containing the part before the separator, the separator itself, and the part after the separator. In this case, since the separator 'cd' is at the beginning of the string 'cd', the part before the separator is an empty string, the separator is 'cd', and the part after the separator is also an empty string, resulting in the tuple ('', 'cd', '').

Question 15

What is the output of the following program :
Print 'abcefd'.replace('cd', '12')
A)ab1ef2
B)abcefd
C)ab1efd
D)ab12ed2

Accepted Answer

The 'replace' method in Python replaces occurrences of a specified substring with another substring. In this case, 'cd' does not exist in 'abcefd', so the string remains unchanged.

Question 16

What will be displayed by the following code?
Def f(value, values):
V = 1
Values[0] = 44
T = 3
V = [1, 2, 3]
F(t, v)
Print(t, v[0])
A)1 1
B)1 44
C)3 1
D)3 44

Accepted Answer

The function `f` modifies the first element of the list `v` to 44. Since lists are mutable, the change is reflected outside the function. The variable `t` is not affected by the function call, so it remains 3. Thus, the output is `3 44`.

Question 17

Predict the output of following python programs
Dictionary1 = {'Google' : 1,'Facebook' : 2,'Microsoft' : 3}
Dictionary2 = {'GFG' : 1,'Microsoft' : 2,'Youtube' : 3}
Dictionary1.update(dictionary2);
For key, values in dictionary1.items():
Print(key, values)
A)Compilation error
B)Runtime error
C)(„Google?, 1)
(„Facebook?, 2)
(„Youtube?, 3)
(„Microsoft?, 2)
(„GFG?, 1)
D)None of these

Accepted Answer

The `update()` method updates `Dictionary1` with key-value pairs from `Dictionary2`, overwriting existing keys. The final dictionary is printed in the order of insertion.

Question 18

What is the output of the following program?
Dictionary1 = {'GFG' : 1,'Google' : 2,'GFG' : 3}
Print(dictionary1['GFG']);
A)Compilation error due to duplicate keys
B)Runtime time error due to duplicate keys
C)3
D)1

Accepted Answer

In Python dictionaries, if a key is repeated, the last value associated with that key is stored, overwriting any previous values. Therefore, 'GFG' is associated with 3, making the output 3.

Question 19

What is the output of the following program?
Temp = dict()
Temp['key1'] = {'key1' : 44, 'key2' : 566}
Temp['key2'] = [1, 2, 3, 4]
For (key, values) in temp.items():
Print(values, end = "")
A)Compilation error
B){„key1?: 44, „key2?: 566}[1, 2, 3, 4]
C)Runtime error
D)None of the above

Accepted Answer

The program creates a dictionary with two keys, 'key1' and 'key2'. The value associated with 'key1' is another dictionary with two keys, 'key1' and 'key2', and the value associated with 'key2' is a list of four integers. The program then iterates over the items in the dictionary and prints the value associated with each key. The output is the values of the dictionary, which are the other dictionary and the list, printed in the order in which they appear in the dictionary.

Question 20

What is the output of the following program?
Data = [2, 3, 9]
Temp = [[x for x in[data]]
For x in range(3)]
Print (temp)
A)[[[2, 3, 9]], [[2, 3, 9]], [[2, 3, 9]]]
B)[[2, 3, 9], [2, 3, 9], [2, 3, 9]]
C)[[[2, 3, 9]], [[2, 3, 9]]]
D)None of these

Accepted Answer

The output is A) because the list comprehension inside the temp variable creates a new list containing the 'data' list for each iteration of the loop, resulting in a list of lists, each containing the 'data' list.
