## Commands
Widgets in guizero can be given a `command` when created, which can be used to call a function when the widget is used.
By using commands you can make your GUI change and take actions when the user interacts with it, for example by clicking a button, selecting an option or typing a message.
### Example
This code will display `hello world` when the button is pressed:
```python
from guizero import App, Text, PushButton
def say_hello():
text.value = "hello world"
app = App()
text = Text(app)
button = PushButton(app, command=say_hello)
app.display()
```
