MySQL Question

Python - No module named 'PyMySQL'

I'm trying to add 'PyMySQL, but it keeps throwing

Traceback (most recent call last):
File "/home/john/workspace/Python/sql/sql.py", line 1, in <module>
import PyMySQL
ImportError: No module named 'PyMySQL'


I tried installing it via pip and running it again, but the error doesnt go away. Any ideas on what is wrong ?

john@john-PC:$ sudo pip install PyMySQL
