Because Python is not a shell script, and should not strive to be like
them. It's a different language.
Furthermore, many of the cases you talk about don't make sense. Shell
script redirections, pipes, etc. all assume there are sensible streams
of data moving around. That makes perfect for a shell, where they
organize programs being run and their input and output, but what does it
mean for Python code in general where no such streams exist?

I think you're getting One Hammer Syndrome. Why not use both, each for
the purposes at which they're best suited?
Besides, when you're running the Python scripts, you've got access to
those all snazzy shell operators that you want to use. Just use them

That's not surprising, since Perl has its heritage in shell scripts.
Perl had its beginnigs as a unification of shell scripting and other
basic UNIX utilities like grep and sed.
