Introduction
In programming, it is common to encounter problems that require us to check if two strings are anagrams of each other. Anagram is a word or phrase made by rearranging the letters of another word or phrase. In this article, we will discuss different techniques to achieve this goal using Python.
The Problem
Before diving into the solutions, let’s understand the problem statement. We are given two strings and we need to check whether they are anagrams of each other or not. Anagram strings have the same characters but in a different order.
Example:
String1: ‘listen’ and String2: ‘silent’ are anagrams of each other. String1: ‘hello’ and String2: ‘world’ are not anagrams of each other.
Solution 1: Sorting
One simple approach to solve this problem is by sorting the characters of both strings and then comparing them. If the sorted strings are equal, then the original strings are anagrams of each other.
Example:
| String1 | String2 | Sorted String1 | Sorted String2 | Result |
|---|---|---|---|---|
| ‘listen’ | ‘silent’ | ‘eilnst’ | ‘eilnst’ | True |
| ‘hello’ | ‘world’ | ‘ehllo’ | ‘dlorw’ | False |
This approach has a time complexity of O(nlogn) due to sorting. It is not the most optimal solution for large strings as it takes more time to execute.
Solution 2: Hash Tables
Another efficient approach is by using hash tables, also known as dictionaries in Python. We can count the frequency of characters in both strings and store them in separate dictionaries. If the dictionaries are equal, then the original strings are anagrams of each other.
Example:
| String1 | String2 | Frequency Dictionary1 | Frequency Dictionary2 | Result |
|---|---|---|---|---|
| ‘listen’ | ‘silent’ | {‘l’:1,’i’:1,’s’:1,’t’:1,’e’:1,’n’:1} | {‘s’:1,’i’:1,’l’:1,’e’:1,’n’:1,’t’:1} | True |
| ‘hello’ | ‘world’ | {‘h’:1,’e’:1,’l’:2,’o’:1} | {‘w’:1,’o’:1,’r’:1,’l’:1,’d’:1} | False |
This approach has a time complexity of O(n) as we only iterate through the strings once to count the frequency of characters.
Conclusion
With the two solutions presented in this article, checking if two strings are anagrams of each other with Python becomes a simple task. However, in terms of efficiency, using hash tables is the better approach as it has a faster runtime. It is essential to understand the problem requirements and implement the appropriate solution.

Python Tips: Checking if Two Strings are Anagrams of Each Other
When working with strings in Python, you might need to check if two strings are anagrams of each other. An anagram is a word or phrase formed by rearranging the letters of another, such as listen and silent. Here are some common questions people have about checking for anagrams in Python:
- What is an anagram in Python?
- How do I check if two strings are anagrams in Python?
- How do I sort a string in Python?
- Can Python check if two strings are anagrams without sorting?
- How do I count the frequency of characters in a string in Python?
An anagram is a word or phrase formed by rearranging the letters of another word or phrase.
You can check if two strings are anagrams in Python by sorting the characters in each string and comparing them. If the sorted strings are equal, then the original strings are anagrams of each other.
You can sort a string in Python using the sorted() function. For example:
string = listensorted_string = sorted(string)print(sorted_string) # Output: ['e', 'i', 'l', 'n', 's', 't']Yes, you can check if two strings are anagrams without sorting by using a dictionary to count the frequency of each character in each string. If the frequency counts are equal, then the original strings are anagrams of each other.
You can count the frequency of characters in a string in Python using a dictionary. For example:
string = listenchar_freq = {}for char in string: if char in char_freq: char_freq[char] += 1 else: char_freq[char] = 1print(char_freq) # Output: {'l': 1, 'i': 1, 's': 1, 't': 1, 'e': 1, 'n': 1}
