Distance calculator

Question

A robot moves in a plane starting from the origin point[0,0].. The robot can move toward UP, DOWN, LEFT, RIGHT. The trace of robot movements is as given following:

UP 5

DOWN 3

LEFT 3

RIGHT 2

The numbers after directions are steps. Write a program to compute the distance current position after sequence of movements.

Answer 1

Hello @

Try this code:

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)

its not working for me and let me know how should we give input

Answer 2

dict= {"x":0, "y":0}
while True:
    a = input("enter your direction for the robot(UP, DOWN)etc: ")
    if a=="UP":
        dict["y"]+=5
    elif a=="DOWN":
        dict["y"]-=3
    elif a=="LEFT":
        dict["x"]-=3
    elif a=="RIGHT":
        dict["x"]+=2
    elif a=="DIST":
        d=math.sqrt(dict["x"]**2 + dict["y"]**2)
        print(d)
        break
    else:
        print("invalid entry, try again")

Please check following code:

from math import sqrt

x0,y0 = 0,0

x1,y1 = 0,0

direction = ' '

while direction != "Calculate":

  if direction == "Up":

    y1=y1+steps

  elif direction == "Down":

    y1=y1-steps

  elif direction == "Right":

    x1=x1+steps

  elif direction == "Left":

    x1=x1-steps

  

  direction = input("Please enter direction as one of Up/Down/Left/Right or Calculate for finding distance: ")

  if direction != "Calculate":

    steps = float(input("Please enter steps: "))

if direction == "Calculate":

    sqrdist = (x1-x0)**2 + (y1-y0)**2

    distance = sqrt(sqrdist)

    print("Distance covered is: " + str(distance))

#Starting position co-ordinates - x=0 and y=0
import math

x, y = 0, 0

while True:
    step = input("Type in UP/DOWN/LEFT/RIGHT (space) step number: ")
    step=step.upper()
    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 of current position from origin is :", c)
