Hi,
Using re might be faster than scanning the same line twice :
=== begin snap
## rewords.py
import re
import sys
def iWordsMatch(lines, word, word2):
reWordOneTwo = re.compile(r".*(%s|%s).*" % (word,word2))
return (line for line in lines if reWordOneTwo.match(line))
for line in iWordsMatch(open("rewords.py"), "re", "return"):
sys.stdout.write(line)
=== end snap
Furthermore, using list comprehension generator (2.4 only I think) and file
iterator, you can scan files as big as you want with very little memory
usage.
