Keywords and Identifiers

Last updated Aug 08, 2021

Keyword

A Python Keyword is a reversed word which you can't use as a name of your variable, class, function, etc. These keywords have a special meaning and they are used for special purposes in the Python programming language.  For example – the Python keyword “while” is used for a while loop thus you can’t name a variable with the name “while” else it may cause a compilation error. There are a total of 36 keywords in Python 3.9.

There are many keywords but these keywords are used most in the python language.

 

Identifiers

An Identifier is a name given to entities like class, functions, variables, etc. It helps to differentiate one entity from another. The variable name is known as an identifier. Identifiers can be a combination of letters in lowercase (a to z) or uppercase (A to Z) or digits (0 to 9) or an underscore  _ . Names like myclass, var_1, and print_this_to_screen, all are valid examples.
