How to map numbers to list elements in python

I have this variable attributes that contains lists:

print(attributes)

    ['glucose_tol', 'age']
    ['glucose_tol', 'age', 'mass_index']
    ['glucose_tol', 'age', 'mass_index']
    ['age']
    ['age']
    ['glucose_tol', 'age']
    ['glucose_tol', 'age']
    []
    ['glucose_tol', 'age']
    ['glucose_tol', 'age', 'mass_index']

What I want is to map glucose_tol to 17.61, mass_index to 1.00 and age to 1.00 and then add these up. So for example [17.61, 1.00] will be 18.61, for ['17.61', '1', '1'] will be 19.61 etc and then add all these up to a number.

I looked at python's map() function but I don't know how to use it in this case, because I have many lists in one variable.

when I do:

  print(type(attributes))
  print(attributes)

I get :

<class 'list'>
['glucose_tol', 'age']
<class 'list'>
['glucose_tol', 'age', 'mass_index']
<class 'list'>
['glucose_tol', 'age', 'mass_index']
and so on...

Here is the code you need:

total = 0
mapping = {
    ”glucose_tol”: 17.61,
    ”age”: 1.0,
    ”mass_index”: 1.0
}
for attr in attributes:
    for item in attr:
        total += mapping[item]

please test this:

mapping = {'glucose_tol': 17.61, 'age': 1, 'mass_index': 1}

values = [
    ['glucose_tol', 'age'],
    ['glucose_tol', 'age', 'mass_index'],
    ['glucose_tol', 'age', 'mass_index']
]

for i in values:
    print(sum([mapping[y] for y in i]))
    # with map
    print(sum(list(map(lambda x: mapping[x], i))))
