大城市里の小女人 提交于 2019-12-12 08:27:12
问题 I have the following python code using the twisted API. def function(self,filename): def results(result): //do something for i in range(int(numbers)) : name = something that has to do with the value of i df = function_which_returns_a defer(name) df.addCallback(results) It uses the Twisted API.
