Python 3 syntax error: '\Users:' --> r'\Users:'
Python 3 syntax error: '\Users:' --> r'\Users:'

Python 3 will treat __\U__ in a string as a Unicode escape and will raise a syntax error so let's use an r'string' instead of a normal 'string'.
* $ __python3 -c "print('\U')__   # SyntaxError: (unicode error)
* $ __python3 -c "print(r'\U')__  # __\U__
