Find Frequency of Characters in Python Last Updated : 14 Nov, 2024 Comments Improve Suggest changes Like Article Like Report In this article, we will explore various methods to count the frequency of characters in a given string. One simple method to count frequency of each character is by using a dictionary.Using DictionaryThe idea is to traverse through each character in the string and keep a count of how many times it appears. Python s = "GeeksforGeeks" freq = {} for c in s: if c in freq: freq[c] += 1 else: freq[c] = 1 print(freq) Output{'G': 2, 'e': 4, 'k': 2, 's': 2, 'f': 1, 'o': 1, 'r': 1} Explanation: We use a dictionary freq to store each character as the key and its count as the value. We loop through the string s and check if the character is already in the dictionary. If it is then increase its count by 1. Otherwise, set its frequency to 1.Let's explore other various methods to find the frequency of each character in String:Table of ContentUsing Counter from collections LibraryUsing a Dictionary ComprehensionUsing Counter from collections LibraryThe collections module has a built-in Counter class to count character frequencies in a string. Python from collections import Counter s = "GeeksforGeeks" # Count character frequency using Counter freq = Counter(s) print(dict(freq)) Output{'G': 2, 'e': 4, 'k': 2, 's': 2, 'f': 1, 'o': 1, 'r': 1} Explanation: Counter(s) counts the frequency of each character in s and returns a Counter object which is a dictionary-like collection. To convert back to dictionary we can wrap the freq with dict()Using Dictionary ComprehensionA dictionary comprehension can also be used to count character frequencies in a concise form. Python s = "GeeksforGeeks" # Count characters using dictionary comprehension freq = {c: s.count(c) for c in s} print(freq) Output{'G': 2, 'e': 4, 'k': 2, 's': 2, 'f': 1, 'o': 1, 'r': 1} Explanation: {char: s.count(char) for char in s} creates a dictionary where each character in s is a key and s.count(c) gives its frequency.

Note: Repetitions of characters is not allowed. Examples: Input : Dict = ["go","bat","me","eat","goal","boy", "run"] arr = ['e','o','b', 'a','m','g', 'l'] Output : go, me, goal.

This involves identifying unique characters and their order of appearance. We are given a string s = "geeksforgeeks" we need to return the non repeating character from the string which is 'r' in this case. This 4 min read Count occurrences of a character in string in Python We are given a string, and our task is to count how many times a specific character appears in it using Python. This can be done using methods like .count(), loops, or collections.Counter. For example, in the string "banana", using "banana".count('a') will return 3 since the letter 'a' appears three 2 min read chr() Function in Python chr() function returns a string representing a character whose Unicode code point is the integer specified. chr() Example: Python3 num = 97 print("ASCII Value of 97 is: ", chr(num)) OutputASCII Value of 97 is: a Python chr() Function Syntaxchr(num) Parametersnum: an Unicode code integerRet 3 min read How To Print Unicode Character In Python?
