Error with double backslash in Windows path in Python

Question

I want to work with paths in Windows in Python 3.3, but I have an error:

FileNotFoundError: [Errno 2] No such file or directory: \'E:\\\\dir\\\\.

Answer 1

Changing '\\' for '/' worked for me. I created a directory named 'a' in C:/ for this example.

>>> (Python interpreter)
>>> import os
>>> os.path.isdir('C:/a/)')
>>> True
>>> os.path.isfile('C:/a/)')
>>> False

Answer 2

If you are using a raw-string, then you do not escape backslashes:

f(r'E:\dir')

---

Of course, this problem (and many others like it) can be solved by simply using forwardslashes in paths:

f('E:/dir')
