Checking if two strings are permutations of each other in Python

# First method
def permutation(s1,s2):
 if len(s1) != len(s2):return False;
 return ' '.join(sorted(s1)) == ' '.join(sorted(s2))


# second method
def permutation1(s1,s2):
 if len(s1) != len(s2):return False;
 array = [0]*128;
 for c in s1:
 array[ord(c)] +=1
 for c in s2:
   array[ord(c)] -=1
   if (array[ord(c)]) < 0:
     return False
 return True
