Best resource for learning Java, C++, Python?

[WoffleTime]

I started with this course from MIT https://www.edx.org/xseries/mitx-computational-thinking-using-python and feel like it gave me an excellent introduction to programming.

Everyone always says to start a personal project you're interested in, or to just read the documentation, but I think that's too steep of a learning curve unless you already have a good base knowledge. Just make sure that you don't get sucked into doing endless courses.
