Files with a .zip or .egg extension can also be added as search paths by selecting Add Zip Archive to Search Path command. Syntax: os.path.relpath(path, start = os.curdir) Parameter: path: A path-like object representing the file system path. The not obvious part IMO is to realise that Path.absolute() is actually not comparable to os.path.abspath (despite the similar name).absolute does not try to clean up .. like abspath, which is usually what the user wants but not really.Path.resolve() is the best function in design, but it suffers from suboptimal implementations in various versions that makes it less useful than it should be. Import os.path.
