Re: [Tutor] reading from stdin

The way I did this was to use sys.stdin.readlines() to get the output

Here is the program:
[code]
import sys, glob
args = sys.stdin.readlines() # found on the net
pat = sys.argv[1]
for i in args:
        if (i.find(pat) != -1):
                print i,
[/code]
My question is am I getting the output from the pipe in the correct
way ? The way Im doing it works (so far) but should I be doing it
another way ?
unless you want the output for some other reason, a more idiomatic way
is:
for line in sys.stdin.readlines():
    # handle the line
I tend to use xreadlines() which does not read the entire input at once. 
 For stdin this make sense, you have no idea how much data will be 
piped in.
