[Tutor] Counting number of occurrence of each character in a string

[Ian Clark]

I would certainly recommend the Counter object from Collections
https://docs.python.org/3.8/library/collections.html#counter-objects

from collections import Counter
x = "ABRACADABRA"
x_counter= Counter(x)
for key, value in x_counter.items():
    print(key,value)
