I have two dictionaries:
fruit = {'apple':15, 'mango':12, 'banana':16, 'kiwi':24} people = {'sam':{'mango':3,'kiwi':12}, 'joy':{'apple':9, 'banana':10, 'kiwi':14}, 'bob':{'mango':8, 'apple':10, 'banana':12}}
For every key in the People dictionary, I want to calculate the percentage of values(fruits count) based on the fruit dictionary broken down by individual fruits and all fruits combined.
This is how the calculation is: {‘sam’:{‘mango’:3/12 = 0.25,’kiwi’:12/24 = 0.5, ‘total’: (3+12)/(12+24) = 0.41}
Finally, my output should look like this:
people = {'sam':{'mango':0.25,'kiwi':0.5, 'total':0.41}, 'joy':{'apple':0.6, 'banana':0.625, 'kiwi':0.58, 'total':0.6}, 'bob':{'mango':0.66, 'apple':0.66, 'banana':0.75, 'total':0.69}}
Can anyone help me how to calculate this?

Answer
You can use a loop, collect the numerator and denominator sums for the grand total and update each value:
for d in people.values(): num = denom = 0 for k,v in d.items(): num += v # sum values for total denom += fruit[k] d[k] = round(v/fruit[k],2) d['total'] = round(num/denom,2)
NB. I’m assuming here that all keys exist in fruit
. If this in not guaranteed use the get
method with a default value.
Output:
{'sam': {'mango': 0.25, 'kiwi': 0.5, 'total': 0.42}, 'joy': {'apple': 0.6, 'banana': 0.62, 'kiwi': 0.58, 'total': 0.6}, 'bob': {'mango': 0.67, 'apple': 0.67, 'banana': 0.75, 'total': 0.7}}
