Python has it's own problems. Not the least of which being it being hundreds of times slower than coreutils. I'll take learning Shell and a handful of coreutils, over praying the sysadmin has successfully navigated/allowed me to navigate all the Python footguns. Also, good luck doing anything embedded where space is at a premium. Not all base systems have/need Python. Everything needs a shell, however.
