Python is Keyword Usage
Let us see a few examples to know how the “is” keyword works in Python.
Compare List Elements using is Keyword
In this example, we will declare two different Python lists of the same elements and compare them using the ‘is’ keyword and the ‘==’ operator.
Python3
# Python program to demonstrate # is keyword x = [ "a" , "b" , "c" , "d" ] y = [ "a" , "b" , "c" , "d" ] print (x is y) print (x = = y) |
Output :
False
True
Python ‘is’ Keyword in For Loop Expression
In this example, we will declare two different objects with the same integer value and then use the ‘is’ keyword with Python if else statement.
Python3
# Python program to demonstrate # is keyword x = 10 y = 10 if x is y: print ( True ) else : print ( False ) |
Output:
True
is keyword in Python
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.
