Question

Assign point_dist with the distance between point (x1, y1) and point (x2, y2). The calculation is: Distance = SquareRootOf( (x2 - x1)² + (y2 - y1)² ). 

Sample output with inputs: 1.0 2.0 1.0 5.0

Points distance: 3.0

Answer 1

import math

print("Hello world")

def point_dist (x1,y1,x2,y2):

xSqr = (float(x1)-float(x2))**2

ySqr = (float(y1)-float(y2))**2

return( math.sqrt(float(xSqr)+float(ySqr)))

print("First Point")

x1 = input("Please input X1 :>");

y1 = input("pLease input Y1 :>")

print("Second Point")

x2 = input("Please input X2 :>")

y2 = input("Please input Y2 :>")

D = point_dist(x1,y1,x2,y2)

print('the distance is ')

print(D)
