I am making a game in Python 3.6.4.

When the player touches the red circle, the player should teleport back to the start. 

**Question 1:** How do I move the turtle to the start if it hits the red circle? 

**My code:**

```
import turtle

wn = turtle.Screen()
wn.bgcolor("black")

player = turtle.Turtle()
player.color("white")
player.speed(0)
player.penup()
player.setposition(100, -110)

enemy = turtle.Turtle()
enemy.color("red")
enemy.shape("circle")
enemy.penup()
enemy.setposition(100, -100)

if player.pos(100, -100):
    player.pos(100, -110)

```

**The error I get is:**

`Traceback (most recent call last):
 File "C:\Users\ruffi\AppData\Local\Programs\Python\Python36-32\behg.p", line 18, in <module>
 if player.pos(100, -100):
TypeError: pos() takes 1 positional argument but 3 were given`

**Question 2:** How do I fix this error?
