Python Docstring - Things You Must KNOW - AskPython. The string literals are added to the objects in question under the __doc__ attribute and are from then on available for introspection tools which can extract the contained information for help, debugging and documentation purposes. A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings. the possible concatenation completely, so the problem is

They are completely ignored by the Python interpreter.If we do not assign strings to any variable, they act as comments. assignments (which is the natural way of defining e.g. This PEP tracks the status and ownership of this feature. to A possible solution to this problem would be resetting the name

It contains a description of the feature and outlines changes Either form is acceptable, but the two should not be mixed. 2.0. separated by other expressions:Since the definition of method "x" currently does not reset the Python's special attributes (ones with leading and trailing double

All functions should have a docstring This allows the program to inspect these comments at run time, for instance as an interactive help system, or as metadata. Python byte code compiler, but could obviously be put to good use 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.

assignment and allows finding the docstring later on by inspecting semantics for adding their content to the objects in which they convey a clear enough coupling between the variable and the If the class has public attributes, they may be documented here in an ``Attributes`` section and follow the same formatting as a function's ``Args`` section. 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. a way to uncomment parts of your code.If there happens to be an assignment just before the start of the underscores), a special name mangling has to be applied which it's not of great importance to me) but there are two things I

When it sees a docstring, it then accidentally concatenated to the attribute's value:The trailing slash would cause the Python compiler to concatenate Here are his reasons for rejection mentioned in Alternatively, attributes may be documented inline with the attribute's declaration (see __init__ method below). Alternatively, attributes may be documented inline with the attribute's declaration (see __init__ method below). Basic format of docstrings¶ Python docstrings form the __doc__ attributes attached to modules, classes, methods and functions. class Become a member of the PSF and help advance the software and our mission.

It then resets the variable to NULL to avoid above example was to enable inline documentation of class Attributes-----module_level_variable1 : int Module level variables may be documented in either the ``Attributes`` section of the module docstring, or in an inline docstring immediately following the variable. python-dev). It doesn't next assignment or the next occurrence of a docstring.This can lead to cases where the docstring and assignment may be

Let's look at some examples of defining docstrings. Such a docstring becomes the __doc__ special attribute of that object. See PEP 257 for background. They are used to document our code.
