I'm currently considering two of them and would like some feedback on best practices. 1. in pkg.__init__.py add: from pkg.mod1 import A in prog.py add: from pkg import A 2. leave __init__.py empty in prog.py add: from pkg.mod1 import A Is there a preference or best practice that would indicate to prefer method 1 or method 2? Are there methods 3, 4, 5, ... that I should consider that are even better? -- Gerald Britton, MCSE-DP, MVP LinkedIn Profile: http://ca.linkedin.com/in/geraldbritton
