Python: Find all anagrams of a string in a given list of strings using Lambda

Last update on December 21 2024 07:31:16 (UTC/GMT +8 hours)

Write a Python program to find all anagrams of a string in a given list of strings using Lambda.

According to Wikipedia an anagram is direct word switch or word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram.

Sample Solution:

Python Code :

# Import the 'Counter' class from the 'collections' module
from collections import Counter

# Create a list 'texts' containing strings
texts = ["bcda", "abce", "cbda", "cbea", "adcb"]

# Create a string 'str' containing characters 'abcd'
str = "abcd"

# Display a message indicating that the following output will show the original list of strings
print("Orginal list of strings:")
print(texts)  # Print the contents of the 'texts' list

# Use the 'filter()' function with a lambda function to filter anagrams of 'abcd' from the list
# Filter elements from 'texts' using the lambda function to keep strings that are anagrams of 'abcd'
# The lambda function checks if the Counter of 'str' (count of characters) is equal to the Counter of each string 'x'
result = list(filter(lambda x: (Counter(str) == Counter(x)), texts))

# Display the anagrams of 'abcd' found in the original list of strings
print("\nAnagrams of 'abcd' in the above string: ")
print(result)  # Print the filtered 'result' list 

Sample Output:

Orginal list of strings:
['bcda', 'abce', 'cbda', 'cbea', 'adcb']

Anagrams of 'abcd' in the above string: 
['bcda', 'cbda', 'adcb']
