You'd want to do one of three things there:

1) use forward slashes
                    "C:/Users/hugo/Desktop/file.txt"
       which Windows will use happily for nearly every purpose.

2) use raw strings
                   r"C:\Users\hugo\Desktop\file.txt"

3) or escape the backslashes:
                     "C:\\Users\\hugo\\Desktop\\file.txt"
