在 python 的 for 循環中將附加值附加到字典的現有鍵

Question

我有一本字典dic = {0: 0, 1: 0, 2: 0, 3: 0, 4: 0, 5: 0, 6: 0, 7: 0, 8: 0, 9: 0}我會就像 append 值在每個循環之后將這些現有鍵作為數組而不覆蓋現有值。 像這樣：

list = [......]
keys_set = list(range(10))
dic = {key: 0 for key in keys_set} 

for index in range(len(data)):
    condition = list[index].numpy()
    for x in (condition):
        for key in keys_set:
            if x == key:
                dic[key].append[index]

但我收到錯誤AttributeError: 'int' object has no attribute 'append'我試過（擴展，append，更新）但它們不起作用。 我希望返回如下所示的內容：

{0: ([24121,  4849, 40312, ...,  8343, 17503, 15662]), 
1: ([25202, 37384, 53119, ..., 42502, 11939, 54489]), 
2: ([47883, 45099,  6391, ..., 17220, 45904,  1735]), 
3: ([36057, 24066, 36887, ...,  2587, 36021, 39961]), 
4: ([23270, 45773, 10778, ..., 33301, 55598, 53125]), 
5: ([40253, 30402, 24574, ..., 37823, 53769, 51425]), 
6: ([48568,  4923,  1986, ...,  6178, 27890, 39086]), 
7: ([35919, 36136, 38468, ..., 39877, 31991, 24692]), 
8: ([23147, 40398,  1745, ..., 16440, 40957, 53170]), 
9: ([ 3785,   583, 15312, ..., 42293, 58852, 46889])}

Answer 1

您需要在字典列表中創建值：

keys_set = list(range(10))
dic = {key: [] for key in keys_set} 

for index in range(len(data)):
    condition = list[index].numpy()
    for x in (condition):
        for key in keys_set:
            if x == key:
                dic[key].append[index]
