You can determine the frequency of each character in a string using Python's collections.Counter or a simple dictionary.
Method 1: Using collections.Counter (Efficient)
from collections import Counter
text = "hello world"
print(dict(Counter(text)))
#Output: {'h': 1, 'e': 1, 'l': 3, 'o': 2, ' ': 1, 'w': 1, 'r': 1, 'd': 1}
Method 2: Manual Counting
def char_frequency(s):
freq = {}
for char in s:
freq[char] = freq.get(char, 0) + 1
return freq
print(char_frequency("hello world"))
# Output: {'h': 1, 'e': 1, 'l': 3, 'o': 2, ' ': 1, 'w': 1, 'r': 1, 'd': 1}
This approach manually counts character occurrences using a dictionary.
Both methods will give you the frequency of each character, including spaces.
