Odd MySQL connection problem

[backseat]

I'm getting:

...
File "/usr/lib/python2.7/dist-packages/MySQLdb/connections.py", line 50, in defaulterrorhandler
    raise errorvalue
OperationalError: (1045, "Access denied for user 'pytrack2'@'localhost' (using password: YES)")

The password, user and database are accessible from the command line.

How can I debug this?

What output can I show here to help?

Thanks,

Keith

Resolution, in case anyone else sees this:

I had imported the database from our production system. The database includes a view. The database username, and thus the view creator name, are different on the production vs development system. That means the view is not visible to the MySQL user on the development system. Found by changing the connection string to use the MySQL root user, which gave more verbose error messages.
