Python's "standard" (and bundled on most platforms) UI tookkit is TCL/TK. However, this has A LOT of drawbacks:
* It's eyesore on a lot of platforms * It's non-pythonic * It just flat out fails on some desktop environments * On linux it requires X, however lots of distros are now using wayland and so on. I think python needs a new "standard" UI toolkit. -- https://mail.python.org/mailman/listinfo/python-list
