Character Frequency - Implementation

The code

Here's the solution:

def char_frequency(text):
    freq = {}
    for char in text:
        freq[char] = freq.get(char, 0) + 1
    return freq

print(char_frequency("hello"))
# {'h': 1, 'e': 1, 'l': 2, 'o': 1}

Same pattern as counting words. The string is just another iterable.
