I have a lot of code that looks like this:
def filter(self, it, defs):
for x in it:
for y in _match_helper(self.key, defs, x[0]):
yield (y, x[1])
def filter(self, it):
for el in it:
try:
if self.compiled.search(el[0]):
yield el
elif not self.skippable:
raise ValidationError
except TypeError:
if not self.skippable:
raise ValidationError
def filter(self, it, ty):
for el in it:
# this may TypeError if ty is not a type nor a tuple of types
# but that's actually the programmer's error
if isinstance(el[1], ty):
yield el
elif not self.skippable:
# and this one is for actual validation
raise ValidationError
It'd be quite nice if dict.items() returned a namedtuple so all these
x[0], x[1], el[0], el[1], etc would instead be x.key, x.value, el.key,
el.value, etc. It would be more readable and more maintainable.
