Extract path like strings from string

In Python is there are easy way to extract strings that look like paths from larger strings?

For example, if:

A = "This Is A String With A /Linux/Path"

What On my way! Looking to extract is:

"/Linux/Path"

I'd also like it to be OS independent, so if:

A = "This is A String With A C:\Windows\Path"

I'd like to extract:

"C:\Windows\Path"

I'm guessing there is a way of doing it with regular expressions looking for / or \ but I just wondered if there was a more pythonic way?

I'm happy to take the risk that / or \ may exist in another part of the main string.

You can split at os.sep and take the results that are longer than one:

import os

def get_paths(s, sep=os.sep):
    return [x for x in s.split() if len(x.split(sep)) > 1]

On Linux / OSX:

>>> A = "This Is A String With A /Linux/Path"
>>> get_paths(A)
['/Linux/Path']

For multiple paths:

>>> B = "This Is A String With A /Linux/Path and /Another/Linux/Path"
>>> get_paths(B)
['/Linux/Path', '/Another/Linux/Path']

Mocking Windows:

>>> W = r"This is A String With A C:\Windows\Path"
>>> get_paths(W, sep='\\')
['C:\\Windows\\Path']
