将两个列表转换成字典？

Question

def dbupdate(self):
    dicDccp = dict(zip(self.dccpdate, self.dccpValue))
    dicDcep = dict(zip(self.dcepdate, self.dcepValue))
    dicDccp = sorted(dicDccp.keys())
    dicDcep = sorted(dicDcep.keys())
    print(type(dicDccp))
    print(type(dicDcep))
    for (k1, v1), (k2, v2) in zip(dicDccp.items(), dicDcep.items()):
        self.Db.dbupdate(self.symbol, self.threshold, k1, v1, k2, v2)

I tried to convert the two lists to a dictionary. But the types of dicDccp and dicDcep were still list s.

Answer 1

The problem is the line dictDccp = sorted(dictDccp.keys())

sorted is a function that takes an iterable object (such as the keys() object that you give it) and returns a list. You are overwriting your dictDccp with this list.

If you were trying to iterate through the keys of the dictionaries in sorted order you could do

for (k1, v1), (k2, v2) in zip(sorted(dictDccp.items()), sorted(dictDcep.items())):
    self.Db.dbupdate(self.symbol, self.threshold, k1, v1, k2, v2)
