I'm assuming you do that so that you don't confuse what a Python built-in method (or function) is,compared to methods (or functions) that you've authored.
It's done more to distinguish classes from methods and attributes. I can't claim any credit though. It's part of the python coding conventions in PEP-8. You can
find the document at http://www.python.org/dev/peps/pep-0008 . The actual coding convention for attribute and variable names is lower_case_separated_by_underscores, but there are projects out there that use initialLowerCamelCase. Pick whatever your current project is using and stick with it. -jeff
