好的，我有兩個元組數組。我想檢查數組二（在其子數組中）是否具有數組一中的匹配元素。如果是這樣，我想將 True 或 False 值附加到Array One的元組中例如結果應該是：[
('Rabbits', [('/home/white', 'white rabbits', False), ('/home/black', 'black rabbits', True), ('/home/green', 'green rabbits', True)]), ('Cats', [('/ans/pink', 'pink cats', True), ('/ans/purple', 'purple cats', False), ('/home/grey', 'grey cats', True)]), ('Hippos', [('/home/red', 'red hippo', False)])]陣列一[
('Rabbits', [('/home/white', 'white rabbits'), ('/home/black', 'black rabbits'), ('/home/green', 'green rabbits')]), ('Cats', [('/ans/pink', 'pink cats'), ('/ans/purple', 'purple cats'), ('/home/grey', 'grey cats')], ('Hippos', ['/home/red', 'red hippo'])),
]陣列二[
('Rabbits', [('/home/black', 'black rabbits'), ('/home/green', 'green rabbits')]), ('Cats', [('/ans/pink', 'pink cats'), ('/home/grey', 'grey cats')]), ('Hippos', [])
]當前嘗試 1：（給定一個數組，每個元素將附加四次 3x false 和 1x True）def parse_selectedmenu(array_one, array_two): # boolean flag used when rendering checkbox 'ticked' in template selected = True not_selected = False index = 0 # array_one = list(array_one) # array_two = list(array_two) final_array = [] for array_one_name, default_items in array_one: final_array.append([array_one_name]) # loop through the ticked "made available" items in post data for array_two_name, custom_items in array_two: # loop through default sub menu items in default menu for default_item in default_items: for custom_item in custom_items: # if a requested menu item exists in default sub menu if default_item[0] == custom_item[0] and default_item[1] == custom_item[1]: if len(default_item) <= 2: mylist = list(default_item) # append selcted against matched menu item in default menu items

看來您在輸入數據中使用括號時存在一些細微的不一致，我冒昧地糾正了這些不一致。完成此操作后，為了真正解決問題，我認為將第二個數組轉換為字典以便于包含測試是有意義的。這給出：
from pprint import pprint
array_1 = [('Rabbits', [('/home/white', 'white rabbits'),
('/home/black', 'black rabbits'),
('/home/green', 'green rabbits')]),
('Cats', [('/ans/pink', 'pink cats'),
('/ans/purple', 'purple cats'),
('/home/grey', 'grey cats')]),
('Hippos', [('/home/red', 'red hippo')])]
array_2 = [('Rabbits', [('/home/black', 'black rabbits'),
('/home/green', 'green rabbits')]),
('Cats', [('/ans/pink', 'pink cats'),
('/home/grey', 'grey cats')]),
('Hippos', [])]
d = dict(array_2)
out = []
for species, tups in array_1:
lst = []
for tup in tups:
if tup in d[species]:
lst.append(tup + (True,))
else:
lst.append(tup + (False,))
out.append((species, lst))
pprint(out)
輸出：
[('Rabbits',
[('/home/white', 'white rabbits', False),
('/home/black', 'black rabbits', True),
('/home/green', 'green rabbits', True)]),
('Cats',
[('/ans/pink', 'pink cats', True),
('/ans/purple', 'purple cats', False),
('/home/grey', 'grey cats', True)]),
('Hippos', [('/home/red', 'red hippo', False)])]

第一個數組中有一些括號拼寫錯誤，我已更正它們。
以下代碼應該可以工作：
l1=[('Rabbits', [('/home/white', 'white rabbits'), ('/home/black', 'black rabbits'), ('/home/green', 'green rabbits')]), ('Cats', [('/ans/pink', 'pink cats'), ('/ans/purple', 'purple cats'), ('/home/grey', 'grey cats')]), ('Hippos', [('/home/red', 'red hippo')]), ]
l2=[('Rabbits', [('/home/black', 'black rabbits'), ('/home/green', 'green rabbits')]), ('Cats', [('/ans/pink', 'pink cats'), ('/home/grey', 'grey cats')]), ('Hippos', []) ]
m=[i[1][k] for i in l2 for k in range(len(i[1]))]
for i in range(len(l1)):
for k in range(len(l1[i][1])):
if l1[i][1][k] in m:
l1[i][1][k]+=(True,)
else:
l1[i][1][k]+=(False,)
print(l1)
