It seems to me that if she can’t install Python then she may not in general be a good candidate.
In my experience a whole lot of programming jobs involves things not directly linked to programming, such as installing languages, deploying projects, dealing with internal tools, and so on. If you lack the wherewithal to install and run python after reading or watching a few tutorials, you may not be cut out for the job.
I say this as a guy who learns very very slowly and who has to work extra hard to get the basics.
