How to replace uppercase with underscore?

I'm new to Python and I am trying to replace all uppercase-letters within a word to underscores, for example:

ThisIsAGoodExample

should become

this_is_a_good_example

Any ideas/tips/links/tutorials on how to achieve this?

Parse your string, each time you encounter an upper case letter, insert an _ before it and then switch the found character to lower case
