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

Python Lambda: Exercise-19 with Solution

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 :

from collections import Counter  
texts = ["bcda", "abce", "cbda", "cbea", "adcb"]
str = "abcd"
print("Orginal list of strings:")
print(texts) 
result = list(filter(lambda x: (Counter(str) == Counter(x)), texts)) 
print("\nAnagrams of 'abcd' in the above string: ")
print(result)

Sample Output:

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

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

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
