calculate distance in python

dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)

from math import sqrt
def main():
	point1x, point1y = eval(input("Please enter coordinates of Point1 (use commas) "))
	point2x, point2y = eval(input("Please enter coordinates of Point2 (use commas)"))
	
	Distance = sqrt((point1x-point2x)**2 + (point1y-point2y)**2)
	print("The distance between this two points is", str(round(Distance, 4))+" units")

import math
p1 = [4, 0]
p2 = [6, 6]
distance = math.sqrt( ((p1[0]-p2[0])**2)+((p1[1]-p2[1])**2) )

print(distance)
