[Larz60+]

to get character count:

from collections import Counter

def CharacterCount(S):
    S = S.strip().replace(' ','')
    return Counter(S)

print(f"\nCounts 'Python is great fun': {CharacterCount('Python is great fun')}")
print(f"Counts 'Good Times': {CharacterCount('Good Times')}\n")

Output:
Counts 'Python is great fun': Counter({'t': 2, 'n': 2, 'P': 1, 'y': 1, 'h': 1, 'o': 1, 'i': 1, 's': 1, 'g': 1, 'r': 1, 'e': 1, 'a': 1, 'f': 1, 'u': 1})
Counts 'Good Times': Counter({'o': 2, 'G': 1, 'd': 1, 'T': 1, 'i': 1, 'm': 1, 'e': 1, 's': 1})
