Why not just sort the strings?

>>> sorted('anagram')
['a', 'a', 'a', 'g', 'm', 'n', 'r']
>>> sorted('nagaram')
['a', 'a', 'a', 'g', 'm', 'n', 'r']
>>> sorted('anagram') == sorted('nagaram')
True

Anagrams are the two different words formed with same characters: For eg: EAT and TEA likewise there can be numerous examples.

One good way to see if give two words or sentences are anagrams is to set a counter array of size 256, and initially set all the values to 0. (This can be a good option if the input is bigger, at least than a few words) Now start reading the first string(word or a sentence), and increment its corresponding ASCII location in the array by one. Repeat this for the complete string.
Now start reading the second string and keep decreasing the corresponding ASCII counter of each letter in the array.
Finally, parse the array; if all the values are zero then the inputs were anagrams otherwise not.
Following is the commented code for the better understanding.

#include<iostream>
#include<string>

using namespace std;

bool is_anagram(string s1, string s2)
{
    //Following statement chechs the base condition; if either of the strings is empty,                                  
    //return False
    if(s1.length() == 0 || s2.length() == 0)
        return false;

    //initializing the counter array and setting it's values to 0
    int counter[256] = {0};

    //Calculating the lengths of both the strings
    int len1 = s1.length();
    int len2 = s2.length();

    //Following is also a base condition that checks whether the strings are equal in 
    //length, if not we return False
    if(len1 != len2)
        return false;

    //Following for loop increments the values of the counter array for the first  
    //string
    for(int i = 0; i < len1; i++)
    {
        counter[s1[i]]++;
    }

    //This for loop decrements the values of the counter array for the second string
    for(int i = 0; i < len2; i--)
    {
        counter[s2[i]]--;
    }
    //Now we check whether the counter array is empty/(or as it was initialized); if               
    //yes then the two strings are anagrams
    for(int i = 0; i < 256; i++)
    {
        if(counter[i] != 0)
            return false;
    }

    return true;
}

Just another solution without using sort:

s1 = "aaabbbccc"
s2 = "abcabcabc"

def are_anagram1(s1, s2):
   return [False, True][sum([ord(x) for x in s1]) == sum([ord(x) for x in s2])]

print are_anagram1(s1,s2)

NB: this works only for alphabet not numerals

>>> s1 = 'vivid'
>>> s2 = 'dvivi'
>>> s3 = 'vivid'
>>> def is_anagram(s1, s2):
...     if s1.lower() == s2.lower():
...         return False
...     return sorted(s1.lower()) == sorted(s2.lower())
...
>>> is_anagram(s1, s2)
True
>>> is_anagram(s1, s3)
False
>>> s2 = 'dvivii'
>>> is_anagram(s1, s2)
False
>>> s2 = 'evivi'
>>> is_anagram(s1, s2)
False
>>> 

Just a thought:

def check_(arg):
        mark = hash(str(set(sorted(arg))))
        return mark

def ana(s1, s2):
        if check_(s1) != check_(s2):
                pass
        elif len(s1) != len(s2):
                pass
        else:
             print("{0} could be anagram of  {1}".format(s1, s2))

This worked for me

str1="abcd"
str2="bcad"
word1=[]
word2=[]
for x in range(len(str1)):
    word1.append(str1[x])
for x in range(len(str2)):
    word2.append(str2[x])
if(len(word1)==len(word2)):
    for letter in word1:
        if letter in word2:
            word2.remove(letter)

if len(word2)==0:
    print "anagram"
else:
    print "not anagram"

You can use the magic Counter from collections library.
From documentation:

It is an unordered collection where elements are stored as dictionary keys and their counts are stored as dictionary values

So, you can initialize a Counter object with a string (a iterable) and compare with another Counter from a string

from collections import Counter

def is_anagram(str1, str2):
   return Counter(str1) == Counter(str2)

To check if two strings are anagrams of each other using dictionaries:
Note : Even Number, special characters can be used as an input

def anagram(s):
    string_list = []
    for ch in s.lower():
        string_list.append(ch)

    string_dict = {}
    for ch in string_list:
        if ch not in string_dict:
            string_dict[ch] = 1
        else:
            string_dict[ch] = string_dict[ch] + 1

    return string_dict



s1 = "master"
s2 = "stream"

a = anagram(s1)
b = anagram(s2)

if a == b:
    print "Anagram"
else:
    print "Not Anagram"

    #An anagram is the result of rearranging the letters of a word to produce a new word. Anagrams are case insensitive

def is_anagram(w1, w2):

You could use the following code it will not count special characters nor it will count digits and will return “they are anagrams” if the total characters have occurred equally in both strings hence will tell the the strings are anagrams or not .

text = input('Enter a string: ')
text1 = input('Enter a string: ')
text,text1 = text.lower(),text1.lower()
count = 0
count1=0
for i in range(97,123):
    if chr(i) in text and chr(i) in text1:
    count1+=1
        if text.count(chr(i)) == text1.count(chr(i)):
             count +=1
if len(text) >= len(text1):
    num1 = len(text)
else:
    num1 = len(text1)
if count == count1:
    print("they are anagrams")
else :
    print("they are not anagrams")

Here’s a solution if you are adamant on using Python dictionary and you can’t use functional programming:

Create a dictionary using comprehension and compare the dictionaries of the two word with a simple == operator.

def isanagram2(wrd1, wrd2):

    wrd1_dict = {k: 0 for k in wrd1}
    wrd2_dict = {k: 0 for k in wrd2}

    for c1, c2 in zip(wrd1, wrd2):
        wrd1_dict[c1] += 1
        wrd2_dict[c2] += 1

    if wrd1_dict == wrd2_dict:
        return True
    return False

Return True answers the question “Is w2 an anagram of a subsequence of w1”

Explanation: In the code below, we can answer two questions: 1) whether or not two strings are anagrams,2) If w2 is an anagram of a sub-sequence of w1. We use O(1) space (constant) and O(n) time. The dictionary d0 can be expanded to include any characters and we remain within O(1) space bound.

def anagrams(w1,w2):
       d0={chr(i):0 for i in range(ord('a'),ord('z'))}
       for char in w1:
           d0[char]+=1
       for char in w2:
           if d0[char]==0:
               return False
           else:
               d0[char]-=1
    return sum([d0[x] for x in d0])==0 #return True (for subseqence anagram)

Simplest shortest solution

def anagram(word1, word2):
    return sorted(word1) == sorted(word2)

check

print(anagram("xyz","zyx"))
>>True

print(anagram("xyz","zyy"))
>>False

This case we check using two containers for each sorted string.

def anagram(s1, s2):
    str1 = ''
    str2 = ''

    for i in s1:
      str1 += i

    for j in s2:
      str2 += j

    if str1 == str2:
      return True

    return False

I think the shortest way can be:

fstr=input("enter first string:")
sstr=input("enter second string:")

if(fstr==sstr[::-1]):
    print("it's anagram")

I think we can get this like this

s1 = "listen"
s2 = "silent"
s1=list(s1);s1.sort()
s2 = list(s2);s2.sort()
if s1 == s2:
   print ("Given Strings are Anagram")
else:
   print ("Given String are not anagrams")

Here’s one typical assignment solution:

def anagram(s1, s2):
""" (str, str) -> bool

Return True if s1 and s2 are anagrams

>>> anagram(s1, s2)
True
"""
    s1 = s1.replace(" ", "")
    s2 = s2.replace(" ", "")

    s1_new = list(s1)

        dupe_found = True
        while dupe_found:
            dupe_found = False
            for i in s1_new:
                for j in s2_new:
                    if i == j:
                        s1_new.remove(i)
                        s2_new.remove(j)
                        dupe_found = True
                        break

return False

Java Code for Anagram

static void anagram(String s1,String s2){
    if(s1.length()!=s2.length()){
        System.out.println("not anagram");
        return;
    }
    else{
        int []arr=new int[256];

        int size=s1.length();
        for(int i=0;i<size;i++){
            arr[s1.charAt(i)]++;
            arr[s2.charAt(i)]--;
        }
        for(int i=0;i<256;i++){
            if(arr[i]!=0){
                System.out.println("not anagram");
                return;
                }
        }
        System.out.println("anagram");
    }
    
}

Not sure if it was proposed up there, but I went with:

def is_anagram(a, b):
    return sorted(a.lower()) == sorted(b.lower())

def areAnagram(s1,s2):
    if len(s1) != len(s2):
        return False
    count = [0]*256
    for i in range(len(s1)):
        count[ord(s1[i])] += 1
        count[ord(s2[i])] -= 1
                       
    for x in count:
        if x != 0: 
            return False
    return True

a = input("Enter a string:")
b = input("Enter b string: ")

print(areAnagram(a,b))

Here a solution using dict comprehension.

def is_anagram(s1, s2):
    return {c:s1.count(c) for c in s1} == {c:s2.count(c) for c in s2}

Solution:

print('Strings are anagrams' if sorted(input("Enter 1st string: "))== sorted(input("Enter 2nd string: ")) else 'Strings are not anagrams')
