Deleting files from pre installed python folder of mac

Is it safe to delete files/folders from the site-packages folder?

/Library/Python/2.7/site-packages/mysql

The read me file in this folder says :

This directory exists so that 3rd party packages can be installed here. Read the source for site.py for more details.

I want to delete the files and folders to get rid of the connector/python i had installed earlier.
