I'm getting an error that has me pretty stumped.
#! /usr/bin/env python3
from sys import modules
from inspect import isclass
from functools import partial
from abc import abstractmethod
from abc import ABC as AbstractClass
class Decoration(AbstractClass):
defaults = {}
def __init__(self, *list, **map):
self.list = list
self.map = map
def __get__(self, caller, owner):
return partial(self.__call__, caller)
@abstractmethod
def __call__(self, decoratee, *list, **map):
pass
@staticmethod
def set_defaults(defaults):
Decoration.defaults = defaults
class Decorator(Decoration):
def __init__(self, *list, **map):
super().__init__(self, *list, **map)
def __call__(self, function, *list, **map):
print(function)
def decorated(*list, **map):
if map:
for decorator in map:
for arguments in map[decorator]:
function = getattr([__name__], decorator)(function, arguments)
return function(*list, **map)
return decorated
@Decorator()
def dummy(*list, **map):
for item in list:
print(item)
for k, v in map:
print('{} {}'.format(k, v))
def main():
dummy({'banana': True})
if __name__ == '__main__':
main()
On the "function = getattr ..." line, I'm getting this error:
UnboundLocalError: local variable 'function' referenced before assignment
I'm confused mainly because the print statement above finds the function's definition as
<function dummy at (address)>
which is correct. Furthermore, deleting that line lets the program run fine and return currently on the next line. As far as I can tell, it's not a syntax problem of getattr. Any ideas?
