title: File paths in Python in the form of string throw errors
body: <p>I need to put a lot of filepaths in the form of strings in Python as part of my program. For example one of my directories is <code>D:\ful_automate\dl</code>. But Python recognizes some of the characters together as other characters and throws an error. In the example the error is <code>IOError: [Errno 22] invalid mode ('wb') or filename: 'D:\x0cul_automate\\dl</code>. It happens a lot for me and every time I need to change the directory name to one that may not be problematic. </p>
