How to find the frequency of every character in a string with Python

Answer 1

def char_frequency(string):
    # Create an empty dictionary to store the frequency of each character
    frequency = {}
     
    for char in string:
        # If the character is already in the dictionary, increment its count
        if char in frequency:
            frequency[char] += 1
        # If the character is not in the dictionary, add it with a count of 1
        else:
            frequency[char] = 1
     
    return frequency
 
 
string = "Python is a general-purpose programming language"

result = char_frequency(string);

for key, value in result.items():
     print(key, value)
