Hello Tutor,
I am having trouble finding a python 3.7.2 download for my MacOS Mojave
10.14.3 released mid 2014.
I would like to use Xcode to learn python.
Is my OS too old?
Please provide guidance.

I like to use paramiko for these types of things. Of course I don't have
all the details but from the info you have provided it seems like you
should be able to do this with ansible itself.

nations I'm slowly getting my head around it
all. I'm sure I'll be back with more questions as soon as I can
formulate them. My biggest problem, which everyone (except this list)
skimmed over was the __init__ and self parts. Now that I've had those

sources to read, I'd be grateful
