Python dictionary is an unordered collection of items. While other compound data types have only value as an element, a dictionary has a key: value pair. Dictionaries are optimized to retrieve values when the key is known.

l = list(map(str, input().split(', ')))
d = {}
d = {l[i+1].upper() : (int(l[i]) if l[i+1] not in d else d[l[i+1]]+int(l[i])) for i in range(0, len(l), 2)}
print(d)
#input : 101, p, 102, o, 302, p, 305, p
