A unicode error with installing win_unc library

I am trying to install a win_unc library and I get the following error:

File "unc_credentials.py", line 36 """
Syntax error: (unicode error) 'unicodescape' codec can't decode bytes in position 340-341: truncated \uXXXX escape    

and this is the code snippet from the unc_credentials.py that is causing the issue:

def __init__(self, username=None, password=None):
    """
    Returns a new `UncCredentials` object. Both `username` and `password` are optional.
    If neither are provided, the new object will mean that credentials are unnecessary.
    `username` must be a string representing a Windows username (logon). Windows usernames
               may include a domain prefix (i.e. "domain\username"). If `username` cannot be
               construed as a valid Windows username, then this will raise an
               `InvalidUsernameError`.
               Note: UNC connections that require authentication will use the username of the
                     currently logged in Windows user unless specifically provided another
                     username.
               Note: Providing `None` and `""` (the empty string) have very different meanings.
                     Usernames cannot be empty.
    `password` must be a string representing a password.
               Note: Providing `None` and `''` (the empty string) have very different meanings.
               The empty string is a meaningful, legitimate password.

    If only the first positional argument is provided and it is already an instance of the
    `UncCredentials` class (either directly or by inheritance), this constructor will clone
    it and create a new `UncCredentials` object with the same properties.
    """    

the very last line with """" is line 36.

It looks like just a comment to me, but when I get rid of it I get another error no commands supplied

And it seems like there is an issue with the triple-double quotation marks on the last line, I may be wrong though.

I have tried playing around with different quotation marks and use 'r' in front of the strings, but I either get the same error or no commands supplied.

I would really appreciate any suggestions on how I can work around or fix this issue.
