    why not just type "python -V" ? Too much stuff about spotlight … 15% of the whole video … sheesh.

    Also, what about Tcl/Tk ? My installer tells me I have to update that as well.

    This is a very easy to follow video – thanks. However, you don't mention one very important thing : will Python3 overwrite Python2 (in usr/bin) which the system needs, or does the installer put Python3 into usr/local/bin so you can have both as necessary?

  9. dirtdirt says:

    1.) So if both Python 2 and 3 are installed, do common packages like numby, scipy, and matplotlib have to be installed for each version? If yes, how would you do that – execute pip install commands within the desired version of python?
    2.) How would the use of Jupyter notebooks be affected by having the two different versions of python?
