Python Coding challenge - Day 87 | What is the output of the following Python Code?

 


Solution and Explanation: 

In Python, the is keyword is used to check if two variables refer to the same object in memory, while the == operator is used to check if the values of the two variables are equal.


In your example:

a = "Hello"

b = "Hello"

print(f"a is b: {a is b}")

print(f"a == b: {a == b}")

The output will be:

a is b: True

a == b: True

This is because string literals (like "Hello") are interned in Python, meaning that the interpreter will reuse the same object in memory for equal string literals. So, both a and b refer to the same string object in memory, and hence a is b is True. The == comparison also evaluates to True because the values of a and b are the same.
