Why use _mysql module and not use MySQLdb directly?

[Marcel Rodrigues]

Another option is PyMySQL [1]. It's developed in the open at GitHub [2].
It's pure Python, compatible with both Python 2 and Python 3. It's DB-API 2
compliant. It also implements some non-standard bits that are present in
MySQLdb, in order to be compatible with legacy code, notably Django
(personally, I consider the use of non-standard API from a DB adapter a
bug, but while the big projects don't fix it, we have to work around it).
