docformatter 0.1.7

Formats docstrings to follow PEP 257.

Formats docstrings to follow PEP 257.

Features

docformatter currently automatically formats docstrings to follow a subset of the PEP 257 conventions. Below are the relevant items quoted from PEP 257.

• For consistency, always use triple double quotes around docstrings.

• Triple quotes are used even though the string fits on 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 BDFL recommends inserting a blank line between the last paragraph in a multi-line docstring and its closing quotes, placing the closing quotes on a line by themselves.

Example

After running:

$ docformatter example.py

this code:

def launch_rocket():
    """Launch
the
rocket. Go colonize space."""


def factorial(x):
    '''

    Return x factorial.

    This uses math.factorial.

    '''
    import math
    return math.factorial(x)


def print_factorial(x):
    """Print x factorial"""
    print(factorial(x))


def main():
    """Main
    function"""
    print_factorial(5)
    if factorial(10):
        launch_rocket()

gets formatted into this:

def launch_rocket():
    """Launch the rocket.

    Go colonize space.

    """


def factorial(x):
    """Return x factorial.

    This uses math.factorial.

    """
    import math
    return math.factorial(x)


def print_factorial(x):
    """Print x factorial."""
    print(factorial(x))


def main():
    """Main function."""
    print_factorial(5)
    if factorial(10):
        launch_rocket()
