word = input("Enter a word")
Alphabet=['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
for i in range(0,26):
print(word.count(Alphabet[i]))
This as of now yields the no. of times each letter that happens including the ones that don't.
How would I list the letters vertically with the frequency close by it, e.g., like the accompanying?
