QUESTIONS

What is the output of the following code snippet?
x = [1, 2, 3]
y = x.copy()
x.append(4)
print(y)

Right Answer:

The copy() method creates a shallow copy of the list, so changes made to the original list “x” will not affect the copied list “y”. Therefore, the output will be [1, 2, 3].

Which data type is used to store a collection of items, where each item is indexed by a key?

Right Answer:

Dictionaries in Python are used to store collections of items where each item is indexed by a key.

Which data type in Python is used to represent a true or false value?

Right Answer:

Booleans in Python are used to represent true or false values.
