How to create list of dictionaries from merging two lists together, where the keys are repeated-CodePudding

I have two lists:

lst = [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]]

I would like to create a list of dictionaries and 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}]

I have tried d = [dict(zip(keys, i)) for i in lst]

but this returns TypeError: zip argument #2 must support iteration

Any help appreciated

You need to iterate over the keys:

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}]

For each element d in keys, you want to create a dictionary created by zipping each element of l with d, so

[dict(zip(d, l)) for d in keys]
