下面,根据反应界定了X阵列。 然后,如果满足了数据阵列的某些条件,我会修改X。 为什么也以同样的方式修改对策?

response = { result : [{ input_1 :[[0, 0], [0, 0], [0, 0], [0, 0]],  input_2 : [[0, 0], [0, 0], [5, 3], [0, 0]]},
                       { input_1 :[[0, 0], [0, 0], [0, 0], [0, 0]],  input_2 : [[0, 0], [6, 7], [0, 0], [0, 0]]},
                       { input_1 :[[0, 0], [2, 5], [0, 0], [0, 0]],  input_2 : [[0, 0], [0, 0], [5, 3], [0, 0]]},
                       { input_1 :[[0, 0], [0, 0], [5, 1], [0, 0]],  input_2 : [[0, 0], [0, 0], [0, 0], [0, 0]]},
                       { input_1 :[[0, 0], [0, 0], [0, 0], [0, 0]],  input_2 : [[0, 0], [0, 0], [5, 3], [0, 0]]},
                       { input_1 :[[0, 0], [0, 0], [0, 0], [0, 0]],  input_2 : [[0, 0], [6, 7], [0, 0], [0, 0]]},
                       { input_1 :[[0, 0], [2, 5], [0, 0], [0, 0]],  input_2 : [[0, 0], [0, 0], [5, 3], [0, 0]]}],
             something_else : [1,2,3]}

x = []
for my_dict in response[ result ]:
    x.append(my_dict[ input_1 ])
    x.append(my_dict[ input_2 ])
data =  [0, 1, 1, 0, 0, 0, 1, 1, 1, 0, 0, 1, 1, 0]
for i, bit in enumerate(x):
    if data[i] == 0:
        del x[i][0:2]
        print(x[i])

我印制了这本书,以方便居住条件到期后作出的反应。 我很期望,如果满足条件,只有x正在删除。 为什么反应也作了修改,而不是仅仅修改x?

最佳回答

x.append(my_dict[data_1]) 首次执行时,x[0]my_dict[投入_1] 系指 同一物体/em>。

If this isn t what you want, you can use list() to create a new list in memory:

for my_dict in response["result"]:
    x.append(list(my_dict["input_1"]))
    x.append(list(my_dict["input_2"]))
