Points to remember-

You cannot use reserved keywords as an identifier name.

Identifiers can contain all the letters (Small, upper both), all the digits from 0 to 9, and underscore.

The identifier name cannot begin with a digit.

Python identifier names are case sensitive and they do not have any limit on the length of the identifier name.
