Yes, he probably did, in a foreign language, which is the entirety of that post you referenced as well. I had previously read that post several times, but I don't know how to program Python, so I don't understand the underlying logic of it.
What I do know is that I have tried several methods Google says are "escaping spaces" to no avail. As you can see in my earlier screenshots, I've tried quotations marks, using a set variable kmVar action with the path (with quotes, without quotes), then using "$KMVAR_kmVar" in qutoes and without quotes, /Library/Frameworks/Python.framework/Versions/3.7/bin/python3 in quotes and without quotes, "/Users/pariah/Dropbox/_Crucial Files/System - Mac/Mixcloud_Uploader/main.py" in quotes and without quotes... As per the discussion in How to escape spaces etc. in when passing variable to shell - #10 by Jack_Brannen .
I get that you're trying to teach a man to fish, but at a certain point, when the man doesn't live near the water or know how to bait a hook yet still needs to eat that day, he has to ask someone to catch him a fish while he learns. I'm asking you, @mrpasini , @ComplexPoint , and @JMichaelTX , to please tell me explicitly what to write to make this thing I've been researching and trying unsuccessfully to solve for myself for more than two weeks work. Please.
You've seen this thread and my posts in the forums the last three years: I do my best to help myself and to learn before I ask for assistance. I'm far out of my league here. I don't want to learn to program in Python. I asked someone to help me solve a problem. The solution was a Python script. Now I need help simply executing that Python script from KM. I hope you will tell me how to do that without responding, again, as if I have some knowledge of Python or Shell programming.
