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 '/'.
