A robot moves in a plane starting from the original point (0,0). The robot can move toward UP, DOWN, LEFT and RIGHT with a given steps. The trace of robot movement is shown as the following: UP 5 DOWN 3 LEFT 3 RIGHT 2 ¡­ The numbers after the direction are steps. Please write a program to compute the distance from current position after a sequen…

robot.py

import math

x, y = 0, 0

while True:
    step = input("Type in UP/DOWN/LEFT/RIGHT #step number: ")

    if step == "":
        break

    else:
        step = step.split(" ")

        if step[0] == "UP":
            y = y + int(step[1])
        elif step[0] == "DOWN":
            y = y - int(step[1])
        elif step[0] == "LEFT":
            x = x - int(step[1])
        elif step[0] == "RIGHT":
            x = x + int(step[1])

c = math.sqrt(x**2 + y**2)

print("Distance:", c)

How give input

input

Give input like this

UP 26 then enter DOWN 26 then enter RIGHT 26 then enter LEFT 36 enter pass "" it will break out from loop and give you the distance.

Hope it is useful.
