Find Frequency of Each Character Program Code

# Python program to find frequency of each character
text = "hello"

# Method 1: Using dictionary
freq_dict = {}
for char in text:
    if char in freq_dict:
        freq_dict[char] = freq_dict[char] + 1
    else:
        freq_dict[char] = 1

# Method 2: Using collections.Counter
from collections import Counter
freq_counter = Counter(text)

print("String:", text)
print("Character frequencies (dictionary):", freq_dict)
print("Character frequencies (Counter):", freq_counter)
