Help me apply this function to secp256k1

reduction(p)

This finds the reduction of a point on the elliptic curve modulo the prime

p – a prime number

OUTPUT:

The point reduced to be a point on the elliptic curve modulo . .

INPUT: 11517998707 self – A point on an elliptic curve.

My code :

Error:

AttributeError: 'EllipticCurvePoint_finite_field' object has no attribute 'reduction'

EXAMPLES:

    E = EllipticCurve([1,2,3,4,0])
P = E(0,0)
P.reduction(5)
(0 : 0 : 1)
Q = E(98,931)
Q.reduction(5)
(3 : 1 : 1)

My code get error:
