[Python] Python class that does integer operations mod n

I am trying to create a Python class that does operations mod n. For example using mod 100:

11*11==21
66+39==5
1+2+3-30==73
2**10==24


This is how I am doing it:

class ModInteger:
def __init__(self, value, mod):

self.mod = mod
self.value = value % mod
return self

def __add__(self, other):
return ModInteger((self.value + other.value) % self.mod, self.mod)
def __sub__(self, other):
return ModInteger((self.value - other.value) % self.mod, self.mod)
def __mul__(self, other):
return ModInteger((self.value * other.value) % self.mod, self.mod)
def __pow__(self, other):
return ModInteger((self.value ** other.value) % self.mod, self.mod)
#...


It works, but is there a less tedious way of doing it?
