Python: Count Characters in String

You can use the Counter class in the collections library to count the occurrences of characters in a string. Here’s an example:

from collections import Counter

s = "hello world"
counts = Counter(s)

for char, count in counts.items():
    print(f"{char}: {count}")

By running the code above, the output result will be:

h: 1
e: 1
l: 3
o: 2
 : 1
w: 1
r: 1
d: 1
