operating system - how to get the path environment-variable separator in python? - stack overflow
When multiple directories need to be concatenated, as in an executable search path, there is an os-dependent separator character. For Windows it's ';', for Linux it's ':'. Is there a way in Python to get which character to split on?
In the discussions to this question How do I find out my python path using python? , it is suggested that os.sep will do it. That answer is wrong, since it is the separator for components of a directory or filename and equates to '\\' or '/'.

regex - python: split string by list of separators - stack overflow
In Python, I'd like to split a string using a list of separators. The separators could be either commas or semicolons. Whitespace should be removed unless it is in the middle of non-whitespace, non-separator characters, in which case it should be preserved.
Taking the above answer, with your test cases, you want to use a regular expression, and one or more separation characters. In your case, the separation characters seem to be ',', '|', ';' and whitespace. Whitespace in python is '\w', so the comprehension is:
