But If I want to use to get a number of the http processes from my
Python program I must use  a popen command e.g.
popen2.popen3('ps -ef | grep "[h]ttpd" | wc -l')
that is I must call an external  command from Python.

The shell does the exact same thing. And by the way: i think you miss a

grep -v grep

after the first grep - otherwise you count the grep itself.

But it creates a zombie.

Try using the subprocess module. It should not require you to call wait yourself.

So my question is:
Is it possible to get a number of the http processes running on Linux
directly from Python ?

Not really, or at least not with less effort & without duplicating system tools functionality.
