Correct Answer: a) 2
Explanation: The // operator performs floor division, which returns the largest integer less than or equal to the result.
Question 02
What does the following Python code output?
x = [“a”, “b”, “c”]
x.append(“d”)
print(x)
a) [“a”, “b”, “c”]
b) [“a”, “b”, “c”, “d”]
c) [“a”, “b”, “d”]
d) Error
Correct Answer: b) ["a", "b", "c", "d"]

Question 03
What does the following Python code return?
print(len([1, 2, 3, 4, 5]))
a) 4
b) 5
c) 6
d) Error
Correct Answer: b) 5
Explanation: The len() function returns the number of elements in the list, which is 5 in this case.
Question 04
What does this Python code return?
print(“Hello, World!”.upper())
a) hello, world!
b) HELLO, WORLD!
c) Hello, World!
d) Error
Correct Answer: b) HELLO, WORLD!
Explanation: The upper() method converts all the letters in the string to uppercase.
Question 05
What will this Python code return?
x = [1, 2, 3, 4]
print(x.index(3))
a) 1
b) 2
c) 3
d) 4
Correct Answer: b) 2
Explanation: The index() method returns the index of the first occurrence of the specified value. The value 3 is at index 2.
Question 06
What does this Python code return?
print(2 ** 3)
a) 5
b) 6
c) 8
d) 9
Correct Answer: c) 8
Explanation: The ** operator is used for exponentiation. 2 ** 3 means 2 raised to the power of 3, which equals 8.
Question 07
What will the following Python code output?
fruits = [“apple”, “banana”, “cherry”]
fruits.sort()
print(fruits)
a) [“apple”, “banana”, “cherry”]
b) [“banana”, “apple”, “cherry”]
c) [“cherry”, “banana”, “apple”]
d) Error
Correct Answer: a) ["apple", "banana", "cherry"]
Explanation: The sort() method sorts the list in ascending alphabetical order.
Question 08
What is the output of this Python code?
print(“abc” + “def”)
a) abc
b) abcdef
c) abc def
d) Error
Correct Answer: b) abcdef
Explanation: The + operator concatenates two strings. "abc" + "def" results in "abcdef".
Question 09
What does this Python code return?
print([1, 2, 3].pop())
a) 1
b) 2
c) 3
d) Error
Correct Answer: c) 3
Explanation: The pop() method removes and returns the last item from the list. In this case, 3 is the last item.
Question 10
What will this Python code output?
print(10 % 3)
a) 1
b) 2
c) 3
d) 0
Correct Answer: a) 1
Explanation: The % operator returns the remainder of the division. 10 % 3 equals 1 because 10 divided by 3 leaves a remainder of 1.
Question 11
What does this Python code return?
print(“Python”.startswith(“P”))
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The startswith() method checks whether a string starts with a specified prefix. "Python".startswith("P") returns True.
Question 12
What is the output of this Python code?
print(list(range(3)))
a) [0, 1, 2, 3]
b) [1, 2, 3]
c) [0, 1, 2]
d) [1, 2]
Correct Answer: c) [0, 1, 2]
Explanation: The range(3) function generates a sequence of numbers starting from 0 up to but not including 3.
Question 13
What will this Python code output?
print(3 == 3.0)
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: In Python, 3 and 3.0 are considered equal because Python performs type coercion for numerical comparison.
Question 14
What does this Python code return?
print(“123”.isdigit())
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The isdigit() method returns True if all characters in the string are digits. "123" contains only digits, so it returns True.
Question 15
What will this Python code output?
print(2 != 3)
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The != operator checks whether two values are not equal. Since 2 is not equal to 3, the result is True.
Question 16
What does this Python code return?
print([1, 2, 3] == [1, 2, 3])
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The == operator compares the values of two lists. Since both lists contain the same values in the same order, the result is True.
Question 17
What will be the result of this Python code?
x = [1, 2, 3]
print(len(x))
a) 1
b) 2
c) 3
d) 4
Correct Answer: c) 3
Explanation: The len() function returns the number of elements in a list. x contains three elements, so the result is 3.
Question 18
What does this Python code output?
x = 5
y = “5”
print(str(x) == y)
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The str() function converts the integer 5 to the string "5", making the comparison True.
Question 19
What does this Python code return?
x = [1, 2, 3]
y = x
y.append(4)
print(x)
a) [1, 2, 3]
b) [1, 2, 3, 4]
c) [4]
d) Error
Correct Answer: b) [1, 2, 3, 4]
Explanation: Both x and y refer to the same list in memory. Modifying y also affects x.
Question 20
What does this Python code output?
x = [1, 2, 3]
y = x.copy()
y.append(4)
print(x)
a) [1, 2, 3]
b) [1, 2, 3, 4]
c) [4]
d) Error
Correct Answer: a) [1, 2, 3]
Explanation: The copy() method creates a shallow copy of the list. Modifications to y do not affect the original list x.
