我得到了以下字典， network_values
network_values = {
0: "CGR cinémas",
1: "Ville de Choisy-le-Roi",
2: "Pathé Gaumont",
3: "UGC",
4: "Cinéode",
5: "Magestic",
6: "Cinéville",
7: "cinebus",
8: "CGR",
9: "Utopia",
10: "écran mobile 74"
}
我有另一本theater_values帶有嵌套串列的字典
theater_values = {
"0":[
"node/4522090127",
1.0,
300.0,
"Saint-Jean-Pied-de-Port",
"nan"
],
"1":[
"node/563839797",
2.0,
239.0,
"Barbezieux-Saint-Hilaire",
"nan"
],
"2":[
"node/5472582580",
"nan",
"nan",
"Lezay",
"nan"
],
"3":[
"node/7623662713",
2.0,
280.0,
"Montaigu-Vendée",
"nan"
],
"4":[
"node/4115072853",
1.0,
274.0,
"Chalonnes-sur-Loire",
"nan"
],
"5":[
"node/5250851417",
3.0,
341.0,
"Thiers",
"nan"
],
"6":[
"way/83676895",
3.0,
534.0,
"Argentan",
"nan"
],
"7":[
"node/502262289",
8.0,
1898.0,
"Tours",
"CGR cinémas"
],
"8":[
"node/3475038904",
"nan",
"nan",
"Saint-étienne",
"nan"

"9":[

"10":[

"11":[

}
其目的是當像的值CGR cinémas中的嵌套串列存在theater_values并且還network_values，我更新theater_values用的鍵network_values。
如果CGR cinémas存在于network_valuesand 中theater_values，我將更新theater_valuesto 0（可能是整數或字符）。
這是我所做的，但它沒有做它應該做的
def proto_csv(theater_values):
network_values = {0: 'CGR cinémas', 1: 'Ville de Choisy-le-Roi', 2: 'Pathé Gaumont', 3: 'UGC', 4: 'Cinéode', 5: 'Magestic', 6: 'Cinéville', 7: 'cinebus', 8: 'CGR', 9: 'Utopia', 10: 'écran mobile 74}
for keys_theaters,vals_theaters in theater_values.items():
for keys_networks,vals_networks in network_values.items():
if vals_theaters == vals_networks:
theater_values[keys_theaters] = str(keys_networks)
return theater_values
我對如何做到這一點感到有些困惑，因為我的代碼沒有給我想要的結果或實際上沒有任何結果......
更新后的結果是這樣的
theater_values = {
"0":[
"node/4522090127",
1.0,
300.0,
"Saint-Jean-Pied-de-Port",
"nan"
],
"1":[
"node/563839797",

uj5u.com熱心網友回復：
第一件事是'écran mobile 74在您粘貼的代碼回傳時關閉字典中的引號SyntaxError。
然后，在if您當前將字典與字串進行比較的陳述句中，運算式永遠不會為真。您想查看字串是否在字典值中，如果是，則更新字典的該元素：
if vals_networks in vals_theaters:
theater_values[keys_theaters][vals_theaters.index(vals_networks)] = str(keys_networks)
這給出了輸出：
