When I am trying to run the code using python 2.7 It's showing the following error

File "pret.py", line 38 SyntaxError: Non-ASCII character '\xc3' in file pret.py on line 38, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Yup i've raised an issue on this already. Check 49. Use these files.
