Widget adaptation to Jupyter Notebook environment of turtle graphics library, that is inspired by Logo programming language, developed by Wally Feurzeig, Seymour Papert and Cynthia Solomon in 1967.
Simulating robotic commands to draw a figure into a clean surface, you can create Turtles to execute their commands, making them draw by according to the commands sent.
[GIF do exemplo de código em funcionamento]
$ pip install ipyxturtle
$ jupyter nbextension install --py ipyxturtle --user
$ jupyter nbextension enable --sys-prefix --py ipyxturtle$ python -m pip install -e .
$ jupyter nbextension install --py ipyxturtle --user
$ jupyter nbextension enable --sys-prefix --py ipyxturtleTo watch every change on javascript module, enter on js/lib and execute yarn watch.
To start a ipyxturtle environment, first do you have to instantiate a Canvas.
from ipyxturtle import Canvas
canvas = Canvas()
canvasDrawing a Canvas inside a notebook cell response.

Then, you can create turtles to help you to create your own figures.
turtle = canvas.create_turtle()[GIF da turtle sendo criada]
You can create more than one turtle, just calling create_turtle() method again! After all, you can start to draw.
| Command | Arguments | Description | Code example |
|---|---|---|---|
| create_turtle() | Returns a Turtle instance associated to the canvas | turtle = canvas.create_turtle() |
| Command | Arguments | Description | Code example |
|---|---|---|---|
| forward(distance) | distance: Integer | Make the turtle draw the line forward in an amount of pixels relative to the distance parameter | turtle.forward(100) |
| backward(distance) | distance: Integer | Make the turtle draw the line backward in an amount of pixels relative to the distance parameter | turtle.backward(100) |
| right(angle) | angle: Integer | Adjusts the turtle's angle by moving the set amount to the right | turtle.right(90) |
| left(angle) | angle: Integer | Adjusts the turtle's angle by moving the set amount to the left | turtle.left(90) |
| color(color_hex) | color_hex: String | Change turtle color line | turtle.color('green') ou turtle.color('#008000') |
| circle(radius) | radius: Integer | Creates a circle stamp with the specified radius | turtle.circle(100) |
| rectangle(width, height) | width: Integer, height: Integer | Creates a rectangle stamp with the specified width and height | turtle.rectangle(100, 200) |
| speed(value) | value: Float | Set Turtle draw speed | turtle.speed(1.5) |
| set_position(x, y) | x: Integer, y: Integer | Moves the turtle to the desired position | turtle.set_position(100, 100) |
