Well, I can't say that I hate Python, but their system of supposedly
"virtual machines" is just a bunch of symlinks between different
developments that are loosely isolated and I am not a fan of all this. As
for the question, I would recommend (if you can) to try in a dummy VM with
a very similar environment. See if it damages your entire virtual ecosystem
or looks stable enough to do it on the real system.
