I'd like get a statistic of how often each loop is used in practice.
My guess is that for loops are at least twice as common as while loops.
I was trying to take a look at the Python's standard libraries --- those
included in a standard installation of Python 3.9.6, say --- to see
which loops are more often used among while and for loops. Of course,
since English use the preposition ``for'' a lot, that makes my life
harder. Removing comments is easy, but removing strings is harder. So
I don't know yet what I'll do.
Try something like
fors = 0
for file in files:
for line in file:
if re.match(r"/s*for .* in ", line):
fors += 1
This excludes comprehensions, which have replaced some for loops.
