Python libraries exist as source code, so you already have it in your Python library directory, I will often put the pdb statements straight into /usr/lib/python2.7/site-packages/sqlalchemy, or if you want to work straight from a git checkout you can clone it from https://github.com/zzzeek/sqlalchemy/ and install it with development flag, e.g. "pip install -e ." > > Thank you for your help. > > Sven > > -- > SQLAlchemy - > The Python SQL Toolkit and Object Relational Mapper > > http://www.sqlalchemy.org/ > > To post example code, please provide an MCVE: Minimal, Complete, and > Verifiable Example.
