__init__ not initializing array

So I'm trying to initialize an array inside the constructor, however it doesn't seem to actually be working as when the program is run, nothing is output.

class Merge():
    def __init__(self):
        self.result = []
 
    def merge(self, left, right):
            left = left
            right = right
            i, j = 0, 0
 
            while i < len(left) and j < len(right):
                if left[i] <= right[j]:
                    self.result.append(left[i])
                    i += 1
                else:
                    self.result.append(right[j])
                    j += 1
 
            if left:
                self.result.extend(left[i:])
            if right:
                self.result.extend(right[j:])
       
            return self.result
 
    def mergesort(self, a):
            if len(a) < 2:
                return a
 
            middle = len(a) / 2
            left = self.mergesort(a[:middle])
            right = self.mergesort(a[middle:])
 
            return self.merge(left, right)
               
m = Merge()
msort = [8,5,3,1,9,6,0,7,4,2,5]
print m.mergesort(msort)
