I usually do this in Perl:
whatever.pl
while(<>) { #do whatever; }
then cat foo.txt | whatever.pl
cat foo.txt | whatever.pl
Now, I want to do this in Python. I tried sys.stdin but I have no idea how to do as I have done in Perl. How can I read the input?
sys.stdin
import sys for line in sys.stdin: # do stuff w/line
