## With Line Numbers, Highlighting, Title, and ReNumbering
### Syntax
```
{YOUR CODE}
```
Note: Highlighting lines uses an absolute number (i.e., the given number of lines sets the length and order starting from 1).
### Example
while True: rate(200) ball.pos = ball.pos + (ball.p/ball.mass)*dt if not (side > ball.pos.x > -side): ball.p.x = -ball.p.x if not (side > ball.pos.y > -side): ball.p.y = -ball.p.y if not (side > ball.pos.z > -side): ball.p.z = -ball.p.z
