Check if Two Strings are Anagram - Python Last Updated : 21 Feb, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report The task of checking if two strings are anagrams in Python involves determining whether the two strings contain the same characters with the same frequency, but possibly in a different order. For example, given the strings "listen" and "silent", they are anagrams because both contain the same characters with identical frequencies, resulting in the output "Yes".Using HashmapThis is the most efficient and preferred method to check for anagrams. It uses a hashmap (dictionary) to count the frequency of each character in both strings and compares the two frequency maps. If both strings have identical character frequencies, they are anagrams. Python from collections import Counter # for character frequency counting s1 = "listen" s2 = "silent" if len(s1) != len(s2): # check length print("No") else: if Counter(s1) == Counter(s2): # compare character counts print("Yes") else: print("No") OutputYes Explanation: If the lengths are equal, Counter(s1) and Counter(s2) create frequency dictionaries for both strings. If they match, it prints "Yes" otherwise, it prints "No".Table of ContentUsing arrayUsing sorted()Using arrayWe know that the strings contain only lowercase English letters (a-z), we can use an array of size 26 to track the frequency of each character instead of using a hashmap. Each character is mapped to an index between 0 and 25 using the ord() function. Python s1 = "listen" s2 = "silent" if len(s1) != len(s2): # check length print("No") else: count = [0] * 26 # array to track character frequencies (a-z) for i in range(len(s1)): count[ord(s1[i]) - ord('a')] += 1 # increment for s1 count[ord(s2[i]) - ord('a')] -= 1 # decrement for s2 if all(x == 0 for x in count): # check if all frequencies are zero print("Yes") else: print("No") OutputYes Explanation: If the lengths are the same, an array count of size 26 is initialized to track letter frequencies. A loop increments indices for characters in s1 and decrements for s2. If all values in count are zero after the loop, it prints "Yes" otherwise, "No."Using sorted()This is the most efficient and simple method to check for anagrams. The idea is to sort both strings and compare the sorted versions. If both sorted strings are equal, they are anagrams. Python s1 = "listen" s2 = "silent" if sorted(s1) == sorted(s2): print("Yes") else: print("No") OutputYes Explanation: If the sorted versions of both strings are equal, it prints "Yes," indicating they are anagrams otherwise, it prints "No." Comment More infoAdvertise with us Next Article Check if Two Strings are Anagram - Python S Striver Follow Improve Article Tags : Python anagram Python-Sorted Practice Tags : anagrampython Similar Reads Python Tutorial - Learn Python Programming Language Python is one of the most popular programming languages.
