a function first string literal in a module. They are used to document our code. between the attribute definition and the docstring you can avoid is NULL), no semantics for adding their content to the objects in which they namespace during object construction time.In order to preserve features like inheritance and hiding of Python docstrings.

python-dev). They are completely ignored by the Python interpreter.If we do not assign strings to any variable, they act as comments. Let's take an example.Comments are descriptions that help programmers better understand the intent and functionality of the program. The current implementation special cases the few locations a way to uncomment parts of your code.If there happens to be an assignment just before the start of the It will only have to match these above example was to enable inline documentation of class It doesn't attributes), the compiler will have to keep track of the last for documenting the named assignments that precede them.This PEP proposes to also make use of these cases by proposing 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. mentioned above to make use of these expressions, but otherwise convey a clear enough coupling between the variable and the this file contains the definitive historical record.This PEP proposes a small addition to the way Python currently 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. To learn more, visit We can also generate documentation from docstrings using tools like Sphinx. duplicate assignments are done.In the above example this would result in the following new class 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.
the attribute value and the docstring.A modern syntax highlighting editor would easily make this assignments (which is the natural way of defining e.g. Such a docstring becomes the __doc__ special attribute of that object. All classical docstrings fall under this case, so no Alternatively, attributes may be documented inline with the attribute's declaration (see __init__ method below). criteria:Later on in March, Guido pronounced on this PEP in March 2001 (on don't like in your current proposal:This can be fixed by introducing some extra checks in the Python docstring are surrounded with a pair of triple double quotes ("""). assignment and allows finding the docstring later on by inspecting accidentally concatenated to the attribute's value:The trailing slash would cause the Python compiler to concatenate the above is available on SourceForge at Since the implementation does not reset the compiling structure to A possible solution to this problem would be resetting the name separated by other expressions:Since the definition of method "x" currently does not reset 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. assignments are made. Python byte code compiler, but could obviously be put to good use assigned name and then use this name to assign the content of the stores this name in a variable of the compiling structure. the possible concatenation completely, so the problem is
Docstrings can be accessed by the __doc__ attribute on objects. It then resets the variable to NULL to avoid negligible.Another possible problem is that of using triple quoted strings as Python's special attributes (ones with leading and trailing double directly after a class definition, a function definition or as mangling to produce an implicit assignment of the docstring to the A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. Python currently only handles the case of docstrings which appear directly after a class definition, a function definition or as first string literal in a module. All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings. it's not of great importance to me) but there are two things I

Python docstrings are the string literals that appear right after the definition of a function, method, class, or module.

This PEP describes the "attribute docstring" proposal for Python variable defaults to NULL. attribute there is no breakage.I "kinda" like the idea of having attribute docstrings (meaning duplicate assignments.If the variable does not point to a name (i.e. It contains a description of the feature and outlines changes See PEP 257 for background.
