Task

Write a function that receives four parameters: x1, y1, x2, y2 which are all floating point values.

The function is called distance and returns (float) the distance between x1,y1 and x2,y2 on the cartesian coordinate plane.

 

Solution:

	import math
	def dist(x1, y1, x2, y2):
	x = x2-x1
	y = y2-y1
	z = (x**2) + (y**2)
	ans= math.sqrt(z)
	return ans
	#MainProgramBelow
	x1 = float(input("Write the x value for the first coordinate"))
	y1 = float(input("Write the y value for the first coordinate"))
	x2 = float(input("Write the x value for the second coordinate"))
	y2 = float(input("Write the y value for the second coordinate"))
	print("The distance in between the two coordinates is:", dist(x1, y1, x2, y2))

Solution using tuples:

	#Quiz09alternative
	import math
	def dist(a,b):
	x = b[0] -a[0]
	y = b[1] – a[1]
	z = x**2 + y**2
	ans= math.sqrt(z)
	return ans
	#MainProgramBelow
	x1 = float(input("Write the x value for the first coordinate"))
	y1 = float(input("Write the y value for the first coordinate"))
	a = (x1,y1)
	x2 = float(input("Write the x value for the second coordinate"))
	y2 = float(input("Write the y value for the second coordinate"))
	b = (x2,y2)
	print("The distance in between", a ,"and", b , "is:", dist(a,b))
