Python TurtleGraphics - Making a randomly moving turtle?

Question

I'm trying to create a randomly moving turtle here by following these steps in a function I've called drunk_turtle():

Repeat the following as many times as you like:

• Randomly choose an integer, called rand_num, from -1 to 1 (i.e. randomly set rand_num to be -1, 0, or 1)
• Make the turtle turn right rand_num * 90 degrees;
• Go forward 5, 10, or 15 --- choose this value at random. 5 = 1*5, 10 = 2*5, 15 = 3*5, ...

How do I make code that does this? I don't really get how to get my random integer or get it to pick randomly 5, 10, or 15. Any help is appreciated. Thanks!

You can find all of that information in the Python random manual.

random.randint(a, b)

Return a random integer N such that a <= N <= b.

So you would do random.randint(-1,1) to get a number from -1, 0, or 1.

To get 5, 10, or 15, just do 5 * random.randint(1,3).

If you had a more complicated set of numbers to choose from -- say (6, 25, or 33) -- you can do random.choice([6, 25, 33]).
