Plus, I think people forget that Python now works pretty well on Windows, and I don't think the same can be necessarily said for Julia. In my University, we support a lot of people on Windows with Python packages - particularly outside of traditonally HPC type areas.
As a final thing - on one occasion last year, I tried to integrate a Julia interpreter into an application - something Python does really well on all platforms. I found that copying the code from the website example verbatim did not work on Windows, didn't appear to have done for the best part of a year, and wasn't in the testing framework. I've just checked and it's still not resolved.
