TypeError: takes exactly 1 argument (2 given) Python Error

The problem is that i have this function:

def fuerza_repulsion(x):
    area = 100 * 100
    k = math.sqrt(area / len(self.grafo[0]))
    return ((k**2 / x) * c2)

and in this line

f_mod = self.fuerza_repulsion(math.sqrt(dx**2 + dy**2))

i have this error:

TypeError: fuerza_repulsion() takes exactly 1 argument (2 given)

How can i fix it?

It looks like your function is part of a class, in which case the first argument of the function needs to be self, the class object itself. (Also, as @SRC pointed out, you generally call class functions 'methods')

So therefore use:

def fuerza_repulsion(self, x):
    area = 100 * 100
    k = math.sqrt(area / len(self.grafo[0]))
    return ((k**2 / x) * c2)
