Hi,
this is very classical example of summing the marks obtained by a student in each terms:
from collections import Counter
term1 = {"physics":20,"chemistry":20,"math":25,"english":25}
term2 = {"physics":25,"chemistry":28,"math":35,"english":30}
term3 = {"physics":30,"chemistry":25,"math":29,"english":34}
sumAllTerms= Counter(term1) + Counter(term2) + Counter(term3)
print(sumAllTerms)
Thanks
