看你需求吧,沒啥毛病,數據也不是很多, 我提供一種方案

from collections import OrderedDict

d_set = OrderedDict.fromkeys(A)

for x in B:
    del d_set[x]

A = d_set.keys()

這種寫法會報錯,如果x 不在A 中就會報錯,這種寫法可以先加個 if 判斷, x 是否在 A 中再執行 A.remove(x)

試試這個簡單的寫法:

#coding=utf-8
A = ['2016-01-01','2016-01-02','2016-01-03','2017-06-01','2017-06-01','2016-03-08','2016-03-08']
B = ['2016-03-02','2016-03-08']
C = []
for a in A:
    for b in B:
        if a == b:
            break
    else:
        C.append(a)
        
print C

from collections import OrderedDict
A = ['2016-01-01','2016-01-02','2016-01-03','2017-06-01','2016-03-08'] B = ['2016-03-02','2016-03-08']
d_set = OrderedDict.fromkeys(A)
對於B 中的x:
