我对Python比较陌生，我的代码存在问题：

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
A = list(range(2))
B = list(range(2))
another_dict= {(a, b) : [[0, 1, 2, 3, 4, 5, 6], [1, 2, 3, 4, 5, 6, 7], [2, 3, 4, 5, 6, 7, 8]] for a in A for b in B}
my_dict = dict()
for a in A:
for b in B:
for c in range(len(another_dict[a, b])):
for day in range(len(another_dict[a, b][0])):
my_dict[(a, b, c, day)] = another_dict.get((a, b))[range(len(another_dict[a, b])).index(c)][range(len(another_dict[a, b][0])).index(day)]
可以采用0到6之间的值，我想用列表中day
（例如，我希望days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]代替(a, b, c, Monday)）
是否可以将密钥（a，b，c，day）更改为d的新密钥（a，b，c，d）？
提前致谢！
答案 0 :(得分：1)
如果您想使代码保持不变，可以使用新密钥创建一个新字典：
new_dict = {}
for d in my_dict:
new_dict[(d[0],d[1],d[2],days[d[3]])] = my_dict[d]
否则，请更改以下行：
my_dict[(a, b, c, day)] = ...
为：
my_dict[(a, b, c, days[day])] = ...
输出：
{(0, 1, 1, 'Friday'): 5, (0, 1, 2, 'Thursday'): 5, (0, 0, 1, 'Saturday'): 6, (1, 0, 1, 'Saturday') ...
答案 1 :(得分：1)
您还可以使用enumerate功能。改变这一行：
for day in range(len(another_dict[a, b][0])):
my_dict[(a, b, c, days[day])] = ...
为：
for day, d in enumerate(days):
my_dict1[(a, b, c, d)] =
由于days列表与another_dict[a, b][0]的大小相同，我可以自由地简化这一行。但我仍然觉得尼克的回答更优雅，更直接。
