The correct example of event-driven code is:
def h1():
t.forward(30)
wn.onkey(h1, "Up")
The example of event-driven code is:
```python
def h1():
t.forward(30)
wn.onkey(h1, "Up")
```
In this example, the `h1` function is defined, which moves the turtle forward by 30 units. The `onkey` method of the `wn` object binds this function to the "Up" key event, so whenever the "Up" key is pressed, the `h1` function will be executed.
The correct answer is:
```
def h1():
t.forward(30)
wn.onkey(h1, "Up")
```
To determine the correct answer, let's analyze each option:
1. `t = turtle.Turtle()`
This line of code creates a Turtle object from the turtle module. However, it does not involve any event-driven programming concepts.
2. `wn = turtle.Screen()`
This line of code creates a Screen object from the turtle module. Again, it does not involve event-driven programming.
3. `wn.setColor("red")`
This line of code sets the color of the screen to red. While it utilizes the turtle module's functions, it is not event-driven.
4. `t.pd()`
This line of code calls the `pd()` method on the Turtle object, which sets the pen down. Like the previous options, it does not involve event-driven programming.
5. `t.speed(0)`
This line of code sets the speed of the Turtle object to 0, which is the fastest speed. While it is related to the Turtle module, it does not involve event-driven programming.
6. `def h1(): t.forward(30) wn.onkey(h1, "Up")`
This code defines a function `h1()` that moves the turtle forward by 30 units. It then uses the `onkey()` method of the Screen object to bind the function `h1()` to the "Up" key event. This is an example of event-driven programming because the function is triggered when the "Up" key is pressed.
7. `import turtle`
This line of code imports the turtle module but does not involve event-driven programming.
8. `for i in range(x): for j in range(y): t.forward(z) t.right(360 / y) t.right(360 / x)`
This code uses nested loops to move the turtle forward and rotate it based on the values of `x`, `y`, and `z`. While it performs certain actions, it does not involve event-driven programming.
Therefore, the correct answer is option 6.
