Documentation

There is just one function remove_hairs() and one decorator remove_hairs_decorator().

remove_hairs()

This function is useful, when you have string and you need to remove some characters from both sides of the string.

>>> from remove_hairs import remove_hairs
>>> remove_hairs(",a-sd,-/")
'a-sd'

By default, the function uses set of characters defined in .HAIRS, which is defined as /:;,- []<>(). You can change that using hairs parameter:

>>> remove_hairs(" - a sd: --", " -")
'a sd:'

remove_hairs_decorator()

As the name say, remove_hairs_decorator() is just decorator for remove_hairs():

@remove_hairs_decorator
def x():
    return ",a-sd,-/"

assert x() == "a-sd"

Or with hairs parameter:

@remove_hairs_decorator(hairs=" -")
def y():
    return " - a sd: --"

assert y() == "a sd:"
