[英]How to create list of dictionaries from merging two lists together, where the keys are repeated
我有兩個清單：
l = [1.1, 1.1, 1.1, 1.1]
keys = [[2, 3, 1, 4], [2, 1, 4, 3], [3, 1, 2, 4], [3, 2, 4, 1]]
我想創建一個字典列表和 output：
d = [{2: 1.1, 3: 1.1, 1: 1.1, 4: 1.1}, {2: 1.1, 1: 1.1, 4: 1.1, 3: 1.1}, {3: 1.1, 1: 1.1, 2: 1.1, 4: 1.1}, {3: 1.1, 2: 1.1, 4: 1.1, 1: 1.1}]
我試過d = [dict(zip(keys, i)) for i in l]
但這會返回TypeError: zip argument #2 must support iteration
任何幫助表示贊賞
對於keys中的每個元素d ，您要創建一個字典，通過使用d壓縮l的每個元素來創建，所以
[dict(zip(d, l)) for d in keys]
您需要遍歷鍵：
l = [1.1, 1.1, 1.1, 1.1]
keys = [[2, 3, 1, 4], [2, 1, 4, 3], [3, 1, 2, 4], [3, 2, 4, 1]]
d = [dict(zip(i, l)) for i in keys]
print(d)
Output：
[{2: 1.1, 3: 1.1, 1: 1.1, 4: 1.1}, {2: 1.1, 1: 1.1, 4: 1.1, 3: 1.1}, {3: 1.1, 1: 1.1, 2: 1.1, 4: 1.1}, {3: 1.1, 2: 1.1, 4: 1.1, 1: 1.1}]
