Convert int to ASCII and back in Python

Question

I\'m working on making a URL shortener for my site, and my current plan (I\'m open to suggestions) is to use a node ID to generate the shortened URL. So, in theory, node 26

Answer 1

ASCII to int:

ord('a')

gives 97

And back to a string:

• in Python2: str(unichr(97))
• in Python3: chr(97)

gives 'a'
