How to rebuild the object with repr?

Question

My code works perfectly except the last part. I want to recreate the object with repr function but it clearly doesn't work. I tried everything here and on the web but i'm still so confuse. Is there any way to do it and if so what is the syntax ?

class Modulo(object):

    def __init__(self, grondtal, waarde = 0):
        self.grondtal = grondtal
        self.waarde = waarde % grondtal

    def __call__(self, m):
        return Modulo(self.grondtal, m)

    def __add__(self, other):
        return Modulo(self.grondtal, self.waarde + other.waarde)

    def __sub__(self, other):
        return Modulo(self.grondtal, self.waarde - other.waarde)

    def __mul__(self, other):
        return Modulo(self.grondtal, self.waarde * other.waarde)

    def __eq__(self, other):
        return self.waarde == other.waarde and self.grondtal == other.grondtal

    def __ne__(self, other):
        return not self.__eq__(other)

    def __str__(self):
        return  '[%s %% %s]' % (str(self.grondtal), str(self.waarde))

    def __repr__(self):
        return '%s' %Modulo(self.grondtal, self.waarde)

Answer 1

You probably want this:

def __repr__(self):
    return "Modulo(%d,%d)" % (self.grondtal, self.waarde)

Or, a little bit more generic:

def __repr__(self):
    return "%s(%d,%d)" % (self.__class__.__name__, self.grondtal, self.waarde)

For example:

>>> m = Modulo(3,2)
>>> repr(m)
'Modulo(3,2)'
