what's wrong with a simple
emit = True
for line in open("q.txt"):
if line == "xyz\n":
emit = True
if emit:
print line,
if line == "abc\n":
emit = False
loop ? (this is also easy to tweak for cases where you don't want to include
the patterns in the output).
to print to a file instead of stdout, just replace the print line with a
f.write call.
