* Single line comment: Python single-line comment starts with a hashtag symbol(#) and lasts till the end of the line. If the comment exceeds one line then put a hashtag on the next line and continue the comment. Python’s single-line comments are proved useful for supplying short explanations for variables, function declarations, and expressions.
* Multi-line comment: Python multi-line comment is a piece of text enclosed in a delimiter (“””) on each end of the comment. There should be no white space between delimiter (“””). They are useful when the comment text does not fit into one line; therefore need to span across lines. Multi-line comments or paragraphs serve as documentation for others reading your code.
* Docstring: Docstring is a type of comment that is used to show how the program works. By convention, the triple quotes that appear right after the function, method or class definition are docstrings (documentation strings). Docstrings are also neglected by the interpreter.
