Three projects

Here are three finished programs. Each is built from what the book already covered: conditions, loops, lists, functions and drawing. Run one, then change it for yourself — that is how it sticks.

Guess the number

The program has a number in mind and you guess it. while repeats the question until the answer matches.

5
7

secret = 7
guess = number(ask("Guess a number from 1 to 10:"))
while guess != secret:
    say("Not that one. Try again")
    guess = number(ask("Once more:"))
say("You got it!")

Not that one. Try again
You got it!

Replace 7 with random(1, 10) and the program picks a new number every run.

A house

The walls are rectangles, and the roof is drawn by the turtle with a fill. First it walks quietly to the top left corner of the wall, and only then goes around the triangle.

background("lightblue")
color("green")
rect(0, 300, 600, 100)
color("white")
rect(220, 180, 160, 120)
color("red")
pen_up()
back(80)
left(90)
forward(20)
right(90)
pen_down()
begin_fill()
repeat 3 times:
    forward(160)
    left(120)
end_fill()

Add a sun with a circle, a door with a rectangle, a label with the street name — the canvas is yours.

A quiz

Every right answer adds a point. Text is compared the same way as numbers: with ==.

Kyiv
4

score = 0
if ask("The capital of Ukraine?") == "Kyiv":
    score = score + 1
if number(ask("2 + 2 = ?")) == 4:
    score = score + 1
say("Your score:", score, "out of 2")

Your score: 2 out of 2

Try it yourself

1. Add a third question to the quiz.

Kyiv
4
Yu

score = 0
if ask("The capital of Ukraine?") == "Kyiv":
    score = score + 1
if number(ask("2 + 2 = ?")) == 4:
    score = score + 1
if ask("What is this language called?") == "Yu":
    score = score + 1
say("Your score:", score, "out of 3")

Your score: 3 out of 3

2. Count how many guesses it took.

5
7

secret = 7
guesses = 1
guess = number(ask("Guess a number from 1 to 10:"))
while guess != secret:
    guesses = guesses + 1
    guess = number(ask("Once more:"))
say("You got it in", guesses, "guesses")

You got it in 2 guesses
