Question 21
What does this Python code return?
print(“Python”.find(“y”))
a) 0
b) 1
c) 2
d) -1
Correct Answer: c) 2
Explanation: The find() method returns the index of the first occurrence of the specified substring. "y" occurs at index 2 in "Python".
Question 22
What will be the output of this Python code?
x = “banana”
y = “apple”
print(x > y)
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: String comparison is done lexicographically based on Unicode values. "banana" comes after "apple", so the result is True.
Question 23
What does this Python code return?
print([1, 2, 3, 4][:2])
a) [1, 2]
b) [2, 3]
c) [3, 4]
d) Error
Correct Answer: a) [1, 2]
Explanation: The slice [:2] returns elements from the start of the list up to but not including index 2, which results in [1, 2].
Question 24
What will this Python code output?
x = [1, 2, 3]
x.insert(1, “a”)
print(x)
a) [1, 2, 3]
b) [1, “a”, 2, 3]
c) [1, “a”, 3]
d) Error
Correct Answer: b) [1, "a", 2, 3]
Explanation: The insert() method inserts an element at a specified index. "a" is inserted at index 1.
Question 25
What does this Python code return?
x = [1, 2, 3]
x.clear()
print(x)
a) []
b) [1, 2, 3]
c) [None]
d) Error
Correct Answer: a) []
Explanation: The clear() method removes all elements from the list, leaving it empty.
Question 26
What is the result of this Python code?
x = [“apple”, “banana”]
x.extend([“cherry”, “date”])
print(x)
a) [“apple”, “banana”, “cherry”, “date”]
b) [“apple”, “banana”]
c) [“cherry”, “date”]
d) Error
Correct Answer: a) ["apple", "banana", "cherry", "date"]
Explanation: The extend() method adds all elements from another list to the end of the current list.
Question 27
What will this Python code output?
x = 10
if x > 5:
print(“Greater”)
else:
print(“Smaller”)
a) Greater
b) Smaller
c) Error
d) None
Correct Answer: a) Greater
Explanation: Since x is greater than 5, the condition evaluates to True, and the program prints "Greater".
Question 28
What does this Python code return?
print(min([3, 1, 2]))
a) 1
b) 2
c) 3
d) Error
Correct Answer: a) 1
Explanation: The min() function returns the smallest element in the list. In this case, the smallest number is 1.
Question 29
What will this Python code output?
x = [10, 20, 30, 40]
print(x[1:3])
a) [20, 30]
b) [10, 20]
c) [30, 40]
d) Error
Correct Answer: a) [20, 30]
Explanation: The slice [1:3] returns elements from index 1 to 3, but not including 3.
Question 30
What does this Python code output?
print(5 + 5)
a) 5
b) 10
c) 15
d) Error
Correct Answer: b) 10
Explanation: The + operator performs addition. 5 + 5 equals 10.
Question 31
What does this Python code return?
print(type([]))
a) <class ‘list’>
b) <class ‘tuple’>
c) <class ‘set’>
d) Error
Correct Answer: a) <class 'list'>
Explanation: An empty list is denoted by [], and its type is <class 'list'>.
Question 32
What is the result of this Python code?
print([1, 2] + [3, 4])
a) [1, 2, 3, 4]
b) [3, 4]
c) [1, 2]
d) Error
Correct Answer: a) [1, 2, 3, 4]
Explanation: The + operator concatenates two lists. [1, 2] + [3, 4] results in [1, 2, 3, 4].
Question 33
What does this Python code output?
x = (1, 2, 3)
print(len(x))
a) 1
b) 2
c) 3
d) Error
Correct Answer: c) 3
Explanation: The len() function returns the number of elements in a tuple. The tuple (1, 2, 3) has three elements.
Question 34
What will this Python code return?
x = set([1, 2, 2, 3])
print(x)
a) {1, 2, 2, 3}
b) {1, 2, 3}
c) [1, 2, 3]
d) Error
Correct Answer: b) {1, 2, 3}
Explanation: A set contains only unique elements. Duplicates are removed automatically.
Question 35
What does this Python code return?
print(“Python”.endswith(“n”))
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The endswith() method checks whether a string ends with the specified suffix. "Python".endswith("n") returns True.
Question 36
What will be the output of this Python code?
x = [1, 2, 3]
y = [1, 2, 3]
print(x is y)
a) True
b) False
c) Error
d) None
Correct Answer: b) False
Explanation: The is operator checks whether two variables point to the same object in memory. In this case, x and y refer to different list objects, so x is y returns False.
Question 37
What does this Python code return?
x = (1, 2, 3)
y = (1, 2, 3)
print(x == y)
a) True
b) False
c) Error
d) None
Correct Answer: a) True
Explanation: The == operator checks whether two variables have the same value. Since both tuples have the same values, the result is True.
Question 38
What will this Python code output?
x = {“a”: 1, “b”: 2}
print(x[“a”])
a) 1
b) 2
c) “a”
d) Error
Correct Answer: a) 1
Explanation: The value associated with the key "a" in the dictionary is 1.
Question 39
What does this Python code return?
print(len({1, 2, 3}))
a) 1
b) 2
c) 3
d) 4
Correct Answer: c) 3
Explanation: The len() function returns the number of elements in the set {1, 2, 3}, which is 3.
Question 40
What will this Python code output?
x = [1, 2, 3]
print(x[-1])
a) 1
b) 2
c) 3
d) Error
Correct Answer: c) 3
Explanation: Negative indexing in Python allows you to access elements from the end of a list. x[-1] refers to the last element, which is 3.
