String is anagram
Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters).
- Use
str.isalnum()
to filter out non-alphanumeric characters,str.lower()
to transform each character to lowercase. - Use
collections.Counter
to count the resulting characters for each string and compare the results.
from collections import Counter def is_anagram(s1, s2): return Counter( c.lower() for c in s1 if c.isalnum() ) == Counter( c.lower() for c in s2 if c.isalnum() ) is_anagram('#anagram', 'Nag a ram!') # True
