Determine an object's package

Question

Is there a way to reliably get an object's package name? I'm trying to programmatically determine if a connector is from mysqldb, pyscopg2, cx_oracle, or pymssql. I had been using the conn.__class__ and regular expression previously but then stumbled when MySQLdb broke the pattern.

psycopg2: <type 'psycopg2.extensions.connection'>

oracle: <type 'cx_Oracle.Connection'>

pymssql: <type 'pymssql.Connection'>

mysqldb: MySQLdb.connections.Connection

I'm wondering if there's a builtin python method of finding a classes' package. Ideally, this would simply return psycopg2, cx_Oracle, pymssql, or MySQLdb

Yes, thank you, Get fully qualified class name of an object in Python was the first thing that came up when I searched also. psycopg2, cx_oracle, and pymssql all return AttributeError: 'Connection' object has no attribute '__module___'

`AttributeError: 'psycopg2.extensions.connection' object has no attribute '__module__'` — Sebastian, Jan 23 '18 at 22:27
Try using `obj.__class__.__module__`, the accepted answer is not correct. — Paul92, Jan 23 '18 at 22:33

Use inspect.getmodule().

You may inspect the module's __package__ after you get the module if it doesn't suffice.

Another option would be to get use inspect.getfile() and search for the known strings.

the inspect.getmodule(conn) returns None for all the connections I'm working with – Sebastian Jan 23 '18 at 22:40
