sum list of dictionary values

Question

I have a list of dictionary in this form :

[
{\'signal_8\': 1, \'signal_1\': 7, \'signal_10\': 5, \'signal_5\': 2, \'signal_2\': 5, \'signal_6\': 3, \'signa         


        

Answer 1

Can you try below code

basedict=siglist[0]
for k in basedict.keys():
    result=[currdict[k] for currdict in siglist]
    endval=sum(result)
    print("Key %s and sum of values %d"%(k,endval))

Output

Key signal_9 and sum of values 12
Key signal_2 and sum of values 15
Key signal_8 and sum of values 3
Key signal_5 and sum of values 6
Key signal_7 and sum of values 24
Key signal_10 and sum of values 15
Key signal_1 and sum of values 21
Key signal_6 and sum of values 9
Key signal_4 and sum of values 27
Key signal_3 and sum of values 18

Note :- As we are sure that all keys in all dictionaries are same this solution works well. If you have a dictionary with non matching elements then it would result in KeyError . So be aware of that limitation
