  • At some level, there will be a need for/while to iterate the string. And an if statement to count a single character Commented Mar 6, 2021 at 16:28

You can use Counter, it returns a dictionary with character as a key and its frequency as its value.

from collections import Counter
x = "abcdasbdd"
print(Counter(x))

Output

Counter({'d': 3, 'a': 2, 'b': 2, 'c': 1, 's': 1})
