Have you used function or class descriptions as documentation strings in your current project?

Yes, in Python, a docstring is widely used to describe functions, classes, and modules. It helps other developers quickly understand the purpose and usage of the code.

Example of a docstring for a function:

def add(a, b):
    """Returns the sum of two numbers a and b."""
    return a + b

The docstring can be accessed at runtime via the __doc__ attribute or using the help() function. This improves code support and maintenance, as well as helps in generating documentation.
