A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. Such a docstring becomes the __doc__ special attribute of that object.

When to use a string literal after a docstring?

String literals occurring immediately after another docstring are called “additional docstrings”. Please see PEP 258, “Docutils Design Specification” [2], for a detailed description of attribute and additional docstrings. For consistency, always use “””triple double quotes””” around docstrings.

When to insert a blank line after a docstring in Python?

What should the first line of a doc string be?

The doc string line should begin with a capital letter and end with a period. The first line should be a short description. If there are more lines in the documentation string, the second line should be blank, visually separating the summary from the rest of the description.

How are indentations removed from a docstring in Python?

Docstring processing tools will strip a uniform amount of indentation from the second and further lines of the docstring, equal to the minimum indentation of all non-blank lines after the first line. Any indentation in the first line of the docstring (i.e., up to the first newline) is insignificant and removed.
