How do you write a module in Python docstring?

How do you write a module in Python docstring?

The docstring for a module function should include the same items as a class method:

1. A brief description of what the function is and what it’s used for.
2. Any arguments (both required and optional) that are passed including keyword arguments.
3. Label any arguments that are considered optional.

What is a module docstring Python?

A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. Such a docstring becomes the __doc__ special attribute of that object. All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings.

What is the use of docstring in a module?

Python documentation strings (or docstrings) provide a convenient way of associating documentation with Python modules, functions, classes, and methods. It’s specified in source code that is used, like a comment, to document a specific segment of code.

How do you write a good docstring in Python?

Best practices

1. All modules, classes, methods, and functions, including the __init__ constructor in packages should have docstrings.
2. Descriptions are capitalized and have end-of-sentence punctuation.
3. Always use “””Triple double quotes.””” around docstrings.
4. Docstrings are not followed by a blank line.

What should be in a Python docstring?

2. Docstrings for Python Functions

1. The docstring for a function or method should summarize its behavior and document its arguments and return values.
2. It should also list all the exceptions that can be raised and other optional arguments.

What is docstring in Python Class 12?

Python Document String (Docstring) is a string literal that is the first statement in a module, function, class, or method.

How are docstring implemented in a Python function?

The docstring for a Python code object (a module, class, or function) is the first statement of that code object, immediately following the definition (the ‘def’ or ‘class’ statement). The statement must be a bare string literal, not any other kind of expression.

What do you write in a docstring?

Write docstrings for all public modules, functions, classes, and methods. Docstrings are not necessary for non-public methods, but you should have a comment that describes what the method does. This comment should appear after the “def” line. PEP 257 describes good docstring conventions.

What is a Python module write one example?

What are modules in Python? Modules refer to a file containing Python statements and definitions. A file containing Python code, for example: example.py , is called a module, and its module name would be example . We use modules to break down large programs into small manageable and organized files.

How do you read a docstring in Python?

Docstrings are accessible from the doc attribute (__doc__) for any of the Python objects and also with the built-in help() function. An object’s docstring is defined by including a string constant as the first statement in the object’s definition.

What is docstring in Python and explain with an example?

As mentioned above, Python docstrings are strings used right after the definition of a function, method, class, or module (like in Example 1). They are used to document our code. We can access these docstrings using the __doc__ attribute.

What are the features of docstring?

A docstring is simply a multi-line string, that is not assigned to anything. It is specified in source code that is used to document a specific segment of code. Unlike conventional source code comments, the docstring should describe what the function does, not how.

What should be the docstrings for a Python module?

The docstrings for Python Modules should list all the available classes, functions, objects and exceptions that are imported when the module is imported. They should also have a one-line summary for each item. They are written at the beginning of the Python file. Let’s look at the docstrings for the builtin module in Python called pickle.

When do I need to print the Python docstring?

It should be printed when the script is executed with missing or wrong parameters. Python module docstring should list all the classes, functions, exceptions, and dependencies on other modules. Python function docstring should specify the behavior, input arguments, return types, and exceptions.

What’s the difference between a docstring and a symbol in Python?

It explains the logic or a part of it used in the code. It is written by using # symbol. Whereas Python Docstrings as mentioned above provides a convenient way of associating documentation with Python modules, functions, classes, and methods.

When to use comments and docstrings in Python?

Also, Docstrings are great for the understanding the functionality of the larger part of the code, i.e., the general purpose of any class, module or function whereas the comments are used for code, statement, and expressions which tend to be small.
