I am using Jupyter Lab, please advise where did I go wrong for the below codes. The codes below are unread to read the data from the cases.

import math

def proximity_p(p, A, B): x_distance = abs(A[0] - B[0])**p y_distance = abs(A[1] - B[1])**p return(x_distance + y_distance)**(1/p)

result = proximity_p(p, A, B) return result

cases= [[1, (-10,20), (20,-30)], [2, (-6,6), (18,-4)], [2, (2,-1,6), (-1,3,-6)], [3, (-3,8,-1,8), (2,2,0,9)], [4, (2,-4,1,0,6),(-2,4,7,4,-2)]]

for p,A,B in cases: print(f"Result: {result:.3f}")
