I used to think this as well. Then I realized I was using Python wrong.
The only reason you string things together in Bash is usually because
Bash really doesn't do much on its own. So you'd do something like:
ps ax | grep blah | grep -v grep | awk ' { print $1; }'
Whereas in Python you could simply execute the ps ax command and then
process the output through generators as I describe in the like in my
previous post.
With the expressive power of generators, it makes up quite nicely for
the lack of easy subprocess piping.
