# Les 1a

**Zoek je rekenmachine op!**

In een eerdere lessenserie heb je een rekenmachine gemaakt. Die gaan we nu verrijken met een interface met knoppen en uitvoer, daar kun je natuurlijk veel meer mee dan met tekst.

**Een mooie User Interface**

Tot nu toe hebben we in de rekenmachine en in ander projecten met tekst gewerkt, bijvoorbeeld tekst als uitvoer met `print()` en tekst als invoer met `input()` Maar met Python kan je ook mooiere applicaties maken met knoppen, invoerveld en meer. Dat gaan we in de komende lessen leren met de library `tkinter.`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://felienne.gitbook.io/codasium/module-4.1-tkinter/les-1/les-1a.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
