Log ALL errors without using python logging library

Question

I am trying to make a python program that others on my team can use without me having to make a GUI. Thus, it is important that the code they interface is super simple and intuitive to the users. I don't want to put logging code in the main program because I think it would confuse them and I don't know what kind of errors they will produce in the main. Is there a way to route ALL errors and warnings (that would be default be printed to STOUT) to a log file without using python logging module ?
