Python os.path.join on Windows - Stack Overflow
https://stackoverflow.com/questions/2422798I don't understand the point of all these "pedantic" solutions. os.sep is useful when you want to manipulate paths without making assumptions about the separator. It's pointless to use with os.path.join() since it already knows the right separator. It's also pointless if you end up needing to explicitly specify the root directory by name (as you can see in your own example).
