A Sublime Text 3 plugin that supports Python documentation search from selections in the editor. Pydoc is fantastic for generating documentation, but the documentation has to be written in the first place. You must have docstrings in your source code as was mentioned by RocketDonkey in the comments: ' This example module shows various types of documentation available for use with pydoc. PyDoc & Other Existing Systems. PyDoc became part of the Python standard library as of release 2.1. It extracts and displays docstrings from within the Python interactive interpreter, from the shell command line, and from a GUI window into a web browser (HTML). Although a very useful tool, PyDoc has several deficiencies, including.

Introduction

The pydoc module automatically generates documentation from Python modules. The documentation can be saved as pages of text on the console, displayed on the web browser, or even as HTML files.

In this article you will be learning methods to view these documentations in various cases and even learn about docstrings that help you create your own documentation for your python scripts.

Now that you know the use of pydoc, let us get started.

Pydoc Sys

Getting Started

The pydoc module comes packaged along with Python, which means you don’t have to download and install it separately.

In order to access pydoc, you can must first import it.

Accessing interactive shell using help() function

You can access the interactive shell in pydoc using it’s help function.

In order to do this, launch your terminal, and enter the python interactive shell.

Pydoc -g

Now, import pydoc and then use the pydoc.help() command to launch the interactive shell.

Example

Now, you can enter the name of the module, datatype, function, classes, etc., to obtain its documentation right from the interactive script.

Viewing documentation from the browser

If you want to view the documentation from the browser, you can do so easily using pydoc.

This time, you need not run the command through python shell. Rather you can provide it arguments and launch it directly.

To do so, launch your terminal and type the below command.

Pydoc Python

This should generate documentation for all the python modules, functions, objects present on your local system on the browser.

You can even search and retrieve specific keywords this way.

Conclusion

You now know how to view and read documentation of various python keywords, functions, modules, methods offline using the pydoc function.

You also learnt how to generate and create your own documentation using docstrings.

It is essential to maintain good documentation while working on large scale projects in order to know what you are doing where and avoid confusions later on in the future. It also helps prevent various unknown or runtime errors.

pydoc is a Python documentation generator. The module basically generates documentation from other Python modules. We can run the module directly from terminal in Ubuntu. In this article, we would discuss how to use Python documentation generator – pydoc.

The functionality of pydoc is pretty similar to the man command-line utility in Ubuntu. Even the built-in help() function in Python uses pydoc module to generate the documentation.

Furthermore, it primarily derives documentation from various modules through docstring and (in case docstring isn’t present) block of comments line in source file. Briggs 1330 repair manual.

Use pydoc – documentation generator

In this section, we would discuss various options available with pydoc3 command-line utility.

Firstly, we would start with writing out an html file for the module. Hence, issue the following in terminal –

For instance,

It would save math.html in current directory.

Secondly, search for a particular keyword –

Pydoc Command

It will provide us a list of modules which contain the <search_term>. Herein, it will only look for synopsis lines of available modules.

For instance,

The output in the terminal may resemble –

Pydoc command

Thirdly, to make the documentation available of all the modules/package inside a web browser –

Once you quit the web browser, it will display the following in terminal –

Press b to launch browser again, or q to quit.

Fourthly, to start an HTTP server on a particular port –

It will start an HTTP server and ask us to launch a web browser. Press b to launch browser, or q to quit.

Alternately, we can also access the documentation through the web browser directly after we have run the above command in terminal. Type the following in address bar of our web browser –

For instance,

Pydoc Syntax

and, in web browser –

Lastly, to generate the documentation in terminal itself of a particular module –

Pydoc Install

For instance,

In conclusion, we have discussed how to generate Python documentation using pydoc module.
