What's the recommended way of adding a docstring for a dictionary parameter? I can see multiple line docstring examples here.
I need to document the input arguments to a function in the docstring. If it's a simple variable, I can use something like:
def func2(a=x, b = y): """ fun2 takes two integers Keyword arguments: a -- refers to age (default 18) b -- refers to experience (default 0) """ If we have dict passed as input argument to function:
def func3(**kwargs): """ takes dictionary as input <Here how to explain them - Is it like?> kwargs['key1'] -- takes value1 <or simply> key1 -- takes value1 """

Declaring Docstrings: The docstrings are declared using ”'triple single quotes”' or “””triple double quotes””” just below the class, method or function declaration. All functions should have a docstring.
The docstrings for Python script should document the script's functions and command-line syntax as a usable message. It should serve as a quick reference to all the functions and arguments.
Python documentation string or commonly known as docstring, is a string literal, and it is used in the class, module, function, or method definition. Docstrings are accessible from the doc attribute (__doc__) for any of the Python objects and also with the built-in help() function.
A Python docstring is a string used to document a Python module, class, function or method, so programmers can understand what it does without having to read the details of the implementation. Also, it is a common practice to generate online (html) documentation automatically from docstrings.
Python documentation string or commonly known as docstring, is a string literal, and it is used in the class, module, function, or method definition. Docstrings are accessible from the doc attribute (__doc__) for any of the Python objects and also with the built-in help () function.
The str.format () function is used to format a specified string using a dictionary. Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics.

The format () method formats the specified value (s) and insert them inside the string's placeholder. The placeholder is defined using curly brackets: {}. Read more about the placeholders in the Placeholder section below. The format () method returns the formatted string. string .format ( value1, value2... ) value1, value2... Required.
Python docstrings As mentioned above, Python docstrings are strings used right after the definition of a function, method, class, or module (like in Example 1). They are used to document our code. We can access these docstrings using the __doc__ attribute.
I generally use the Google docstring style, so a dictionary parameter would look like:
def func(a_dict): """Some function to do something to a dictionary. Args: a_dict (dict of str: int): Some mapping, I guess? """ ... A function that takes **kwargs (note: this is not quite the same as having a dictionary parameter), would look like:
def func(**kwargs): """Some function to do stuff to arbitrary keyword arguments. Args: **kwargs: Arbitrary keyword arguments. Keyword Args: <kwarg_name> int: A description <kwarg_name_2> str: Another description <...> """ ... If there are specific parameters that should be present (e.g. your key1), they should be separate, not rolled into **kwargs.
In Python 3.x, you can also use function annotations:
def func(a_dict: dict): """Some function to do something to a dictionary.""" ... From Python 3.5, you can be even more explicit using typing:
from typing import Mapping def func(a_dict: Mapping[str, int]): """Some function to do something to a dictionary.""" ... For those using PyCharm: You can configure your default docstring formats in:
Preferences -> Tools -> Python Integrated Tools -> Docstrings as of version 2019 the allowed options are: Plain, Epytext, reStructuredText, NumPy, Google. This functionality will automatically add a docstring skeleton once you've typed three double quotes " and hit enter.
