The find on it's own is obviously more efficient, which is why the times are lower. You don't want to use "*.py" in the grep though, as grep uses regular expressions and not globbing, so "\.py$" will get you the same results (the "\" is needed to escape the ".", which represents a single-character wildcard, and the "$" is needed to anchor the search to the end of the name, otherwise any ".py" in the middle of names will be picked up as well).
