The return code:: 0 -- Success! Annotations are not enforced they are meant as a more generic stepping stone for different use cases but are immediately obvious in the signature. Quotes should not be included. Environments The Python extension automatically detects Python interpreters that are installed in standard locations. An object that supports the protocol can be converted to a or file system path by calling the function; and can be used to guarantee a or result instead, respectively. As a compromise the brief description could be placed before the declaration and the detailed description before the member definition. It will also extract the accompanying docstrings, and compile it all into well structured and easily readable documentation for your project. This may differ from the file name for the executable for some platforms.

If is also possible to document an attribute outside of a class directive, for example if the documentation for different attributes and methods is split in multiple sections. Also, the module provides three key function constructors: , , and. Must return an from its method. Comments are little snippets of text embedded inside your code that are ignored by the Python interpreter. For longer descriptions you often will find the need for some more structure, like a block of verbatim text, a list, or a simple table.

Python Docstrings

documenting python code

It is not supposed to cover all bases, and for more advanced topics please see Sphinx documentation and other sources. The description should include similar information to that described for function. Think about anything that may be confusing to you down the road and make sure to capture those in either comments, docstrings, or the readme. Each framework also has specific settings, such as arguments that identify paths and patterns for test discovery. Normally, names in these roles are searched first without any further qualification, then with the current module name prepended, then with the current module and class name if any prepended. Documentation can be pretty light on these types of projects. Most of these entities are not assigned any special markup, but the preferred spellings are given here to aid authors in maintaining the consistency of presentation in the Python documentation.

Autodocumenting your Python code with Sphinx

See the sphinx documentation for more details. Security Considerations and Other Concerns Some modules provided with Python are inherently exposed to security issues e. Make generous use of blank lines where applicable; they help group things together. While it can take up more lines than the previous example, it allows the developer to include a lot more information about a method, function, or class. Public and Open Source Projects Public and Open Source projects are projects that are intended to be shared with a large group of users and can involve large development teams. This guide will be less useful for authors using the Python documentation tools for topics other than Python, and less useful still for authors not using the tools at all.

Python Project Documentation Using Sphinx

This directive should be nested in a class directive. For this to work, the docstrings must of course be written in correct reStructuredText. It is believed that overcoming this performance issue would make the implementation much more complicated and therefore costlier to maintain. . The following section describes how and when to comment your code.

Remember that comments are designed for the reader, including yourself, to help guide them in understanding the purpose and design of the software. For a quick install, use and. The description should include similar information to that described for function. The role text should not include trailing parentheses to enhance readability. The deprecated option can be given with no value to mark a module as deprecated; it will be designated as such in various locations then.

The name should be fully qualified i. The ellipsis for the secondary interpreter prompt should only be used sparingly, where it is necessary to clearly differentiate between input lines and output lines. Debugging No more print statement debugging! Note that a blank line ends a documentation block in this case. Now you understand the background of docstrings. The default Python prompt of the interactive shell when entering code for an indented code block, when within a pair of matching left and right delimiters parentheses, square brackets, curly braces or triple quotes , or after specifying a decorator. What makes Python special is that it is possible to create custom metaclasses.

You can configure and use snippets provided by an extension. Note that, except for built-in Python names and names located in the same module, you need to provide a fully qualified object's name for cross-reference, e. People learn faster with concrete, motivating examples that match the context of a typical use case. Examples of text files are files opened in text mode 'r' or 'w' , , , and instances of. The price you pay for not putting the documentation block directly before or after an item is the need to put a structural command inside the documentation block, which leads to some duplication of information. A comment is denoted by the hash character and extends to the end of the line.
