How to make dictionary from list-CodePudding

I have this variables:

fab_centrum = ['A', 'B'] 
sales_line = ['1AA', '2BB', '3CC', '1AA', '2BB', '3CC']
keys = ['feasibility_score', 'capacity_score']
feasibility_score = [10,30,40, 10,30,40]
capacity_score = [50,60,70, 50,60,70]

And I would like to make dic with this structure

    bach = {
                A: {'1AA': {
                  feasibility_score: 10,
                  capacity_score: 50,
                  }
                  '2BB': {
                  feasibility_score: 10,
                  capacity_score: 50,
                  }
                   }
                  
           B: {'1AA': {
                  feasibility_score: 10,
                  capacity_score: 50,
                  }
....
                }
    
    
    }

I know I can use something like

batch = dict.fromkeys(fab_centrum, sales_line)

But I dont know how to make dict with nested values like my structue. I am new to python

CodePudding user response：

Is the result below what you want instead?

It looks strange that sales_line, feasibility_score, and capacity_score have duplicate elements inside...but feel free to add them back as long as they have the same length so that zip() won't cut some elements off.

from collections import defaultdict

fab_centrum = ['A', 'B']
sales_line = ['1AA', '2BB', '3CC']
keys_ = ['feasibility_score', 'capacity_score']
feasibility_score = [10, 30, 40]
capacity_score = [50, 60, 70]

batch = defaultdict(dict)
for sl, fs, cs in zip(sales_line, feasibility_score, capacity_score):
    for char in fab_centrum:
        batch[char][sl] = {keys_[0]: fs, keys_[1]: cs}

print(batch)

Result:

{
'A': 
    {
    '1AA':{'feasibility_score': 10, 'capacity_score': 50}, 
    '2BB':{'feasibility_score': 30, 'capacity_score': 60}, 
    '3CC':{'feasibility_score': 40, 'capacity_score': 70}
    }, 

'B': 
    {
    '1AA': {'feasibility_score': 10, 'capacity_score': 50}, 
    '2BB': {'feasibility_score': 30, 'capacity_score': 60}, 
    '3CC': {'feasibility_score': 40, 'capacity_score': 70}
    }
}
