Question 01
Which Python function can be used to return the absolute value of a number?
a) abs()
b) round()
c) int()
d) float()
Correct Answer: a) abs()
Explanation: The abs() function returns the absolute value of a number. It removes any negative sign, leaving only the magnitude of the number.
Question 02
What will be the result of the following code snippet?
x = 10
y = 5
print(x // y)
a) 0
b) 2
c) 5
d) 1
Correct Answer: b) 2
Explanation: The // operator performs floor division, meaning it divides the numbers and rounds down to the nearest whole number. 10 // 5 results in 2.
Question 03
What is the output of the following Python code?
print(“Hello”[1])
a) H
b) e
c) l
d) o
Correct Answer: b) e
Explanation: Strings in Python are zero-indexed, meaning the first character is at index 0. So "Hello"[1] accesses the second character, which is 'e'.
Question 04
What will be the output of this code?
print(2 ** 3)
a) 6
b) 8
c) 9
d) 12
Correct Answer: b) 8
Explanation: The ** operator is used for exponentiation. 2 ** 3 means 2 raised to the power of 3, which equals 8.
Question 05
Which Python function is used to read input from the user?
a) input()
b) read()
c) scan()
d) get()
Correct Answer: a) input()
Explanation: The input() function reads a line of text entered by the user and returns it as a string.
Question 06
What is the result of this expression?
result = “Python” + “3”
print(result)
a) Python
b) Python3
c) 6
d) Error
Correct Answer: b) Python3
Explanation: The + operator concatenates strings. "Python" + "3" results in the string 'Python3'.
Question 07
What does the following Python code return?
len([1, 2, 3, 4, 5])
a) 4
b) 5
c) 6
d) 3
Correct Answer: b) 5
Explanation: The len() function returns the number of elements in a list. [1, 2, 3, 4, 5] contains 5 elements, so the result is 5.
Question 08
What does the following code return?
name = “Alice”
print(name.upper())
a) ALICE
b) alice
c) A
d) Error
Correct Answer: a) ALICE
Explanation: The upper() method converts all lowercase characters in a string to uppercase. 'Alice' becomes 'ALICE'.
Question 09
What does this code do?
numbers = [1, 2, 3]
numbers.append(4)
print(numbers)
a) [1, 2, 3]
b) [1, 2, 3, 4]
c) [1, 2, 4]
d) Error
Correct Answer: b) [1, 2, 3, 4]
Explanation: The append() method adds an item to the end of a list. In this case, the number 4 is added to the list [1, 2, 3].
Question 10
What will be the result of this Python code?
x = 5
y = 10
x, y = y, x
print(x, y)
a) 5 10
b) 10 5
c) 0 0
d) Error
Correct Answer: b) 10 5
Explanation: The code swaps the values of x and y. After the swap, x holds the value 10 and y holds the value 5.
Question 11
What does this code return?
print(10 % 3)
a) 1
b) 3
c) 10
d) 0
Correct Answer: a) 1
Explanation: The % operator returns the remainder of the division. 10 % 3 results in 1, because 10 divided by 3 gives a remainder of 1.
Question 12
What is the correct way to define a function in Python?
a) function myFunc():
b) def myFunc():
c) create myFunc():
d) func myFunc():
Correct Answer: b) def myFunc():
Explanation: Functions in Python are defined using the def keyword followed by the function name and parentheses.
Question 13
What does this code output?
print(type(5.0))
a) <class ‘int’>
b) <class ‘float’>
c) <class ‘str’>
d) <class ‘complex’>
Correct Answer: b) <class 'float'>
Explanation: The type() function returns the type of the given object. 5.0 is a floating-point number, so its type is <class 'float'>.
Question 14
What will this code return?
list1 = [1, 2, 3]
list2 = list1
list2.append(4)
print(list1)
a) [1, 2, 3]
b) [1, 2, 3, 4]
c) [4]
d) Error
Correct Answer: b) [1, 2, 3, 4]
Explanation: In Python, lists are mutable and variables can refer to the same object. Since list2 is a reference to list1, appending to list2 will also modify list1.
Question 15
What is the output of this code?
print(bool(0))
a) True
b) False
c) 0
d) Error
Correct Answer: b) False
Explanation: In Python, 0 is considered False when converted to a Boolean. Non-zero numbers are considered True.
Question 16
What is the result of this Python code?
print(2 * 3 ** 2)
a) 36
b) 18
c) 12
d) 9
Correct Answer: b) 18
Explanation: Exponentiation is done before multiplication, so 3 ** 2 = 9, and then 2 * 9 = 18.
Question 17
Which of the following is the correct syntax for a comment in Python?
a) // This is a comment
b) /* This is a comment */
c) # This is a comment
d) <– This is a comment –>
Correct Answer: c) # This is a comment
Explanation: In Python, comments start with the # symbol. Anything after the # on the same line is ignored by the interpreter.
Question 18
What will this code output?
name = “Bob”
print(name * 3)
a) BobBobBob
b) Bob 3
c) Bob
d) Error
Correct Answer: a) BobBobBob
Explanation: In Python, the * operator can be used to repeat a string a specified number of times. In this case, 'Bob' is repeated 3 times.
Question 19
What will the following Python code return?
print(bool(“False”))
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: In Python, non-empty strings are considered True when evaluated in a Boolean context, even if the string is "False".
Question 20
Which of the following data types is immutable in Python?
a) List
b) Dictionary
c) Set
d) Tuple
Correct Answer: d) Tuple
Explanation: Tuples in Python are immutable, meaning their elements cannot be changed once the tuple is created. Lists, dictionaries, and sets are mutable.
