print(dic_of_genres) `

I can not understand why my dictionary doesn’t update in each loop. Could any body help me?

You don’t need to go over each item. Note that I also added a try except in case x have different elements than dic_of_genres

for i in range(0,n):
    x= [item.capitalize() for item in input().split()]
    for genre in set(x):
               try:
                     dic_of_genres[genre] += x.count(genre)
               except KeyError:
                     pass

print(dic_of_genres)
