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

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value:

Example:

def tips_map_values(obj, fn):
  ret = {}
  for key in obj.keys():
    ret[key] = fn(obj[key])
  return ret
users = {
  'Owen': { 'user': 'Owen', 'age': 29 },
  'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}

Output:

{'Owen': 29, 'Eddie': 15}
