解决方案

我希望这个反例有所帮助。

class counter:
    def __init__(self):
        self.counts = {}
    def count(self,thing):
        try:
            self.counts[thing] += 1
        except:
            self.counts[thing] = 1


data = [1,2,3,5,4,3,56,6,1,23,151,51,1,1,1,1,2,3,4,2]
c = counter()

[c.count(k) for k in data]
print(c.counts)
