I have the results of an optimization run in the form found in the following

How can I multiply the dictionary values of the keys FEq_(i,_j,_k,_l) with
preexisting values of the form A[i,j,k,l]?
For example I want the value of key 'FEq_(0,_0,_2,_2)' multiplied with
A[0,0,2,2], the value of key 'FEq_(0,_0,_4,_1)' multiplied with A[0,0,4,1] etc.
for all the keys present in my specific dictionary.
I have been trying to correspondingly multiply the dictionary values in the
form of
varsdict["FEq_({0},_{1},_{2},_{3})".format(i,j,k,l)]
but this is not working as the indexes do not iterate consequently over all
their initial range values, they are the results of the optimization so some
elements are missing. I also could not find something of a similar nature where
I looked.
Thank you for the help!
Iterate over the keys in varsdict and, for each key, extract the indexes.
With an example:
>>> key = 'FEq_(0,_0,_2,_2)'
>>> key
'FEq_(0,_0,_2,_2)'
>>> key.split('(')[1]
'0,_0,_2,_2)'
>>> key.split('(')[1].split(')')[0]
'0,_0,_2,_2'
>>> key.split('(')[1].split(')')[0].split(',_')
['0', '0', '2', '2']
Now convert them to ints and assign to variables:
>>> i, j, k, l = map(int, key.split('(')[1].split(')')[0].split(',_'))
Now you can get A[i,j,k,l].
