Having worked on a large python code base as well I can tell you that sometimes it's hard. Look at the types, determine if they're instance of and try build small test runs around existing code before you modify it. python tools for visual studio is sweet and may give some help with getting around, as will pycharm. If figuring out where logs are or other configuration details are hard to find get them into configuration files. I guess you can draw the high level of how it fits together but start small, pick a class or method and follow it through. Oh, enjoy it. python was lots of fun for me
