Well, I tell you to write utf-8 text files, following a well known coding standard for your language (which is PEP-8 for Python) and show me the git repository with your code. I don't care which text editor _you_ use, which git client, or which Python interpreter. If you want to use XCode you can go ahead. You like web guis instead of bash, no problem. No need to learn my tool chain.
