Well, it would be something like (easy example):

echo -e 'line1\nline2\nline3' | python -c '
import sys
for line in sys.stdin:
        print line'

That works now (with bash). I get the text into python and can do there
whatever I want. Awk/Sed/grep or whatever kind of tasks.

My problem, I didn't find the solution to just write the code after the
-c '...' including newlines. Sooo easy, but I didn't find that solution
(not even after hours doing curious stuff:)

PS: would there be a smarter way to get the
stdin lines into a loop?
