Other folks have mentioned glob.glob(), which will work fine for
things like "*.txt". If you want something more flexible, for
instance all the *.c and *.h files that mention printf,
you'd want to iterate on the output of something like
	find . -name '*.[ch]' -exec grep -l printf {} \;
and if you wanted to do something like that in Python, you'd want
to know about commands.getoutput(). Specifically, you'd want to
write something like this:
	import commands
	for file in commands.getoutput(
		"find . -name '*.[ch]' -exec grep -l printf {} \;"):
	 process(file)
So commands.getoutput() is good to know about if you need a little
more flexibility than glob.glob().

Resistance is futile. Capacitance is efficacious.
