String is anagram
Python, String · Nov 2, 2020
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.Counterto 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
