Agree, however I like to stress the "don't make me unnecessary read with care"
rule. Meaning if I read that line, I have to read it carefully to make sure I
understand what is happening, the following would not do that although syntax
wise equal:
def length_between_min_max(password):
return(mud.minpass <= len(password) <= mud.maxpass)
def is_valid_password(password):
valid = True
if not length_between_max_min(password):
valid = False
if some_other_test(password):
valid = False
return(valid)
This I can read, typically I would not even read what the function
length_beteen_max_min does as long as there is no bug in it because, it is
perfectly english clear what the intention is.
