Keywords are words reserved for special purposes in a programming language, e.g. del, while, for etc. Whereas, Identifiers are names given to variables, classes, functions etc. e.g. ‘balance’, ‘Vehicle’, ‘add’ etc. A keyword can’t be chosen as an identifier.

Indentation is used in python to create blocks of code. Statements at same indentation level are part of same block/suite.
