Keywords and identifiers in python

 Python Keywords

Keywords are reserved words with a predefined meaning. These words can not be used as a function name, variable name, class name, etc. They're written in lower case except for True, False, and None and are case-sensitive.

An identifier is a stoner- defined name used to identify realities like class, functions, variables, etc. They're used to separate one reality from another.

The identifier is a combination of characters, integers, and a special symbol underscores. Underscore can be used formulti-word variables likecount_one,container_2, etc.
Python is a case-sensitive programming language that makes identifiers also case-sensitive. For illustration, Count and count are two different identifiers in Python.

It's advised to give a meaningful name to the identifier to make the law accessible. For illustration, a variable to store the count of figures can be named “ count” rather of “c.”
