python cast object to int

I am using the numpy module to retrieve the position of the maximum value in a 2d array. But this 2d array consists of MyObjects. Now I get the error:

TypeError: unorderable types: int() > MyObject()

I tried to override the int function with this code:

def int(self): return self.score 

But this does not solve my problem. Do I have to convert my 2d array of MyObjects into a 2d array of integers, do I have to extend the Integer object (if this is possible in python) or can I override this int() function in another way?

[EDIT]

The full object:

class MyObject: def __init__(self, x, y, score, direction, match): self.x = x self.y = y self.score = score self.direction = direction self.match = match def __str__(self): return str(self.score) def int(self): return self.score 

The way I call this object:

 def traceBack(self): self.matrix = np.array(self.matrix) maxIndex = self.matrix.argmax() print(self.matrix.unravel_index(maxIndex))

Try to use

... def __int__(self): return self.score ... test = MyObject(0, 0, 10, 0, 0) print 10+int(test) # Will output: 20 

in your MyObject class definition.

The max function takes a key that is applied on the elements. that's where you put score

Typically :

a = max(my_list, key=score)
