writing a docstring in python

Docstrings may extend over multiple lines. Python docstrings are the string literals that appear right after the definition of a function, method, class, or module. It will revolutionize working with free-form text, the way numpy did for arrays, pandas did for tabular data, and scikit-learn did for machine learning.. The… 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. Example: Examples can be given using either the ``Example`` or ``Examples`` sections. For example,As mentioned above, Python docstrings are strings used right after the definition of a function, method, class, or module (like in Whenever string literals are present just after the definition of a function, module, class or a method, they are associated with the object as their Now, let's look at docstrings for the built-in function Single line docstrings are the documents that fit in one line.Multi-line docstrings consist of a summary line just like a one-line docstring, followed by a blank line, followed by a more elaborate description.The PEP 257 document provides the standard conventions to write multi-line docstrings for various objects.They are written at the beginning of the Python file.Let's look at the docstrings for the builtin module in Python called Here, we can see that the docstring written at the beginning of the As you can see, we have included a short description of what the function does, the parameter it takes in and the value it returns. Everybody has written good pieces of code, that needed to be reviewed two weeks later and nobody understood why or how it works. It is a special multiline string, thus you have to include it between three sets of quotes, not just one. Along with docstrings, Python also has the built-in function help() that prints out the objects docstring to the console. Writing Python Documentation Introducing the docstring. To learn more, visit We can also generate documentation from docstrings using tools like Sphinx. Even months later. Docstring Formats. # -*- coding: utf-8 -*-"""Example Google style docstrings.This module demonstrates documentation as specified by the `Google Python Style Guide`_. Dear Python developer, start writing docstrings now! It is also what’s Sphinx style uses the syntax of a lightweight markup language Although the order of these keywords is not fixed, it is (again) a convention to keep the above order throughout your entire project. The docstrings for a Python package is written in the package's __init__.py file. These are built-in strings that, when configured correctly, can help your users and yourself with your project’s documentation. As already pointed out in a previous article titled Commenting Python Code you have learned that documentation is an essential, and a continuous step in the process of software development. The string literal is embedded to the function Suppose we have a Person.py file with the following code:Here, we can use the following code to access only the docstrings of the The docstrings for a Python package is written in the package's We can write docstring in many formats like the reStructured text (reST) format, Google format or the NumPy documentation format. It should contain all the available modules and sub-packages exported by the package. If you are using VS code, the Python Docstring extension can be used to auto-generate a docstring snippet once a function/class has been written. Article continues below the advertisement. Proper documentation ensures that you're able to read and review your code weeks, even months later.
