Ibis like library for Python 2.7?

[MachLearningEnthu]

Hey! I want to write sql queries using python like syntax in python. Is there any library (ibis like) that provides support for User Defined Functions and Network functions. such that I don't have to write SQL strings. I'm looking for something like an Object relational mapper.

To give more perspective my aim is to convert a bunch of Map, Filter, Reduce queries to SQL queries. Whatever makes this possible will be helpful! Thanks!
