Python: The resulting array of type string does not match

I want to make a program to group words consisting of the same characters in an array, but the results don’t match when using the Python programming language

Example problem: Suppose I have 3 arrays of type string as follows:

oe1 = ["abc", "def"];
oe2 = ["asd", "cab", "fed", "eqw"];
oe3 = ["qwe", "efd", "bca"];

Note: The order of the array or the elements doesn’t matter, the important thing is that they are grouped.

Output example:

[abc, cab, bca]
[asd]
[def, fed, efd]
[eqw, qwe]

But I try to use coding like this the results are not appropriate:

oe1 = ["abc", "def"];
oe2 = ["asd", "cab", "fed", "eqw"];
oe3 = ["qwe", "efd", "bca"];

anagram_list = []
for word_1 in oe1:
  for word_2 in oe2:
      for word_3 in oe3:
        if word_1 != word_2 != word_3 and (sorted(word_1)==sorted(word_2)==sorted(word_3)):
            anagram_list.append(word_1 + word_2 + word_3)
print(anagram_list)

my output is like this:

['abccabbca', 'deffedefd']

How do I make it match the example output above?

>Solution :

Here is one way to perhaps solve your problem:

1. Create a function that takes three lists of words as input and returns a list of lists of anagrams, grouped by input list.

def group_anagrams(oe1, oe2, oe3):
    # Create a dictionary where the keys are the sorted version of each word
    # and the values are lists of the words that have the same characters.
    anagrams = {}
    
    # Loop over each word in each input list.
    for words in [oe1, oe2, oe3]:
        for word in words:
            # Sort the word to create a unique key for each set of anagrams.
            key = ''.join(sorted(word))
            
            # Add the word to the list of anagrams for this key.
            if key in anagrams:
                anagrams[key].append(word)
            else:
                anagrams[key] = [word]
    
    # Return the values of the dictionary (i.e. the lists of anagrams) as a list of lists.
    return anagrams.values()

2. Use the function to group the anagrams in your example.

oe1 = ["abc", "def"]
oe2 = ["asd", "cab", "fed", "eqw"]
oe3 = ["qwe", "efd", "bca"]

anagram_lists = group_anagrams(oe1, oe2, oe3)

# Print the result.
for anagrams in anagram_lists:
    print(anagrams)

This should output the following:

[abc, cab, bca]
[asd]
[def, fed, efd]
[eqw, qwe]

Hope this helps!
