I’m trying to list directories of smb NAS drive using Python, but getting below error,

 >>> import os
 >>> os.listdir(r"//nasxxx/aaaa/yyyy/" )
     Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     FileNotFoundError: [Errno 2] No such file or directory: 
     '//nasxxx/data/yyyy/'

Able to connect the drive thru explorer locally and files are present, but not thru python list directories.
