can i add the docs for a lambda function on same line? in python

To add documentation for a lambda function in Python on the same line, you can use a docstring immediately after the lambda expression itself. Here's an example:

main.py
square = lambda x: x**2  # Single-line lambda function with docstring

square.__doc__ = "This function returns the square of a number."

137 chars
5 lines

In this example, the square lambda function has a docstring that describes what it does. By assigning a string to the __doc__ attribute of the lambda function, you can add documentation to it.

It's important to note that while the docstring can be added to the lambda function, lambda functions are typically used for small, anonymous functions, and therefore, extensive documentation may not be necessary or common practice.

Remember to follow the PEP 257 conventions for writing docstrings in Python, which includes a one-line summary followed by a blank line and optional additional paragraphs.

main.py
"""
This is a docstring for the lambda function.

Additional description can be written here.
"""
98 chars
6 lines

Keep in mind that although adding documentation to a lambda function is possible, it's often more natural to use regular functions for complex logic that requires detailed documentation.
