This code passes all the tests however it's wrong as in case of s = "hel" and t = "hll" it returns True

class Solution:
  def isAnagram(self, s, t):
    # TODO: Write your code here
    if len(s) != len(t):
      return False
    
    l = list(s)

    for c in t:
      if c not in l:
        return False

    return True
