Python Programs - String

Find the frequency of each character - Python Program

Example 1 :

Python 
from collections import Counter
text = "banana"
freq = Counter(text)
print(freq)

Output

 
OUTPUT  :
Counter({'a': 3, 'n': 2, 'b': 1})

Example 2 :

Python 
def character_frequency(input_string):
    """
    Calculates the frequency of each character in a given string.

    Args:
        input_string (str): The string for which to calculate character frequencies.

    Returns:
        dict: A dictionary where keys are characters and values are their frequencies.
    """
    frequency_dict = {}
    for char in input_string:
        frequency_dict[char] = frequency_dict.get(char, 0) + 1
    return frequency_dict

# Example Usage:
text = "hello world"
char_counts = character_frequency(text)
print(f"Character frequencies in '{text}':")
for char, count in char_counts.items():
    print(f"'{char}': {count}")

# Another Example:
sentence = "Python Programming"
sentence_counts = character_frequency(sentence)
print(f"\nCharacter frequencies in '{sentence}':")
for char, count in sentence_counts.items():
    print(f"'{char}': {count}")

Output

 
OUTPUT  :
Character frequencies in 'hello world':
'h': 1
'e': 1
'l': 3
'o': 2
' ': 1
'w': 1
'r': 1
'd': 1

Character frequencies in 'Python Programming':
'P': 2
'y': 1
't': 1
'h': 1
'o': 2
'n': 2
' ': 1
'r': 2
'g': 2
'a': 1
'm': 2
'i': 1
