Python is Keyword

The “is” keyword in Python is used to test object identity. The “is keyword” is used to test whether two variables belong to the same object. The test will return True if the two objects are the same else it will return False even if the two objects are 100% equal.

Note: The == relational operator is used to test if two objects are the same.

How is the ‘is’ keyword implemented in Python

The is a keyword in Python has the following syntax:

a is b
# Using if statement
if a is b:
    statement(s)

In programming, a keyword is a “reserved word” by the language that conveys special meaning to the interpreter. It may be a command or a parameter. Keywords cannot be used as a variable name in the program snippet. Python language also reserves some of the keywords that convey special meaning. In Python, keywords are case-sensitive.
