The best way to improve it would be to clarify readibility. Why 6
times instead of 5 or 7? Are they retries?
MAX_RETRIES = 6 # defined in RFC-3141592
for _ in range(MAX_RETRIES):
if successful(do_thing()):
break
else:
error_condition()
or because someone likes the number 6?
MY_FAVORITE_NUMBER = 6
for _ in range(MY_FAVORITE_NUMBER):
print(f"I love the number {MY_FAVORITE_NUMBER}!")
or days of the week that aren't Sunday?
for day in calendar.c.iterweekdays():
if day == calendar.SUNDAY: continue
do_thing()
or is it because it's the number of whole columns that fit?
screen_cols = 80 # get this from curses?
chars_per_col = 13
for _ in range(screen_cols // chars_per_col):
do_thing()
or because that's how many people there are in a paticular grouping?
family = "Dad Mom Sis Brother Me Baby".split()
for _ in family:
do_thing()
Note how each of those conveys what "6" means, not just some
arbitrary number.
