So in Windows, you see:

so in Python, we have to use exactly the same path with

But since I know it's a path and not a file, I just write without trailing \.
Indeed. There's never a need to put a backslash on the end of
a path, as long as you always use os.path functions or

unicode strings useless for common path literals. For example:
