## Fractal python turtle

In this section, we will learn **about the fractal turtle** in Python Turtle.

**Fractal python turtle **is used to make geometrical shapes with different scales and sizes. In this, it makes repeating shapes in geometry form which works on a different scale and size it is not same in shape.

**Code:**

In the following code, we have used the fractal python turtle which indicated to make geometrical shapes. To create this we import the turtle library.

We use **speed(), penup(), pendown(), forward(), left() goto()**, **getscreen(), and bgcolor()** functions to make this geometry shape.

**speed()**is used to give the speed at which we are creating a geometry shape.**penup()**is used to stop the drawing.**pendown()**is used to start the drawing.**goto()**is used to move the turtle.**forward()**is used to move the turtle forward.**left()**is used to move the turtle to left direction.

```
from turtle import *
import turtle
tur = turtle.Turtle()
tur.speed(6)
tur.getscreen().bgcolor("black")
tur.color("cyan")
tur.penup()
tur.goto((-200, 50))
tur.pendown()
def star(turtle, size):
if size <= 10:
return
else:
for i in range(5):
turtle.forward(size)
star(turtle, size/3)
turtle.left(216)
star(tur, 360)
turtle.done()
```

**Output: **

In the following output, we can see the different geometry shapes and different scales that we can see in this gif, We use **speed(), penup(), pendown(), forward(), left() and goto()** functions to make this geometry shape.

## Fractal tree python turtle

In this section, we will learn about **how to create a fractal tree turtle** in a python turtle.

In this, we are creating a tree using python fractal we created sub-branches (Left and right) and we shorten the new sub-branches until we reach the minimum end to create a tree.

**Code:**

In the following code, we import the turtle module **from turtle import ***, **import turtle** for creating this fractal tree.

To create a tree we assign the x-axis and y-axis that defined the acute angle between the branch of Y.

We assigned the **speed()** function that helps to draw the shape in what speed a user has assigned.

**speed()**is used to define the speed of the pen to draw the shape.**y-axis()**is used to plot a Y**pencolor()**is used for setting color according to color level.

```
from turtle import *
import turtle
speed('fastest')
right(-90)
angle = 30
def yaxis(size, lvl):
if lvl > 0:
colormode(255)
pencolor(0, 255//lvl, 0)
forward(size)
right(angle)
yaxis(0.8 * size, lvl-1)
pencolor(0, 255//lvl, 0)
lt( 2 * angle )
yaxis(0.8 * size, lvl-1)
pencolor(0, 255//lvl, 0)
right(angle)
forward(-size)
yaxis(80, 7)
turtle.done()
```

**Output:**

After running the above code, we get the following output in which we can see the fractal tree is created with size 80 and level 7.

## Fractal recursion python turtle

In this section, we will learn **about fractal recursion **in python turtle.

Recursion is the process of repeating units in a similar way fractal is used to generate an infinite amount of copies of pictures that form a fractal pattern.

**Code:**

In the following code, we imported a turtle library we have defined the title to a window with the name **“Python Guides”** assigning the **bg_color** and giving the screen height and width.

We define the **drawline()** which is drawing from pos1 to pos2 (Position is a phrase of pos) after that we assigned the** recursive()** which is used to generate multiple copies of the same picture.

```
from turtle import *
import turtle
speed = 5
bg_color = "black"
pen_color = "red"
screen_width = 800
screen_height = 800
drawing_width= 700
drawing_height = 700
pen_width = 5
title = "Python Guides"
fractal_depth = 3
def drawline(tur, pos1, pos2):
tracing the algorithm.
tur.penup()
tur.goto(pos1[0], pos1[1])
tur.pendown()
tur.goto(pos2[0], pos2[1])
def recursivedraw(tur, x, y, width, height, count):
drawline(
tur,
[x + width * 0.25, height // 2 + y],
[x + width * 0.75, height // 2 + y],
)
drawline(
tur,
[x + width * 0.25, (height * 0.5) // 2 + y],
[x + width * 0.25, (height * 1.5) // 2 + y],
)
drawline(
tur,
[x + width * 0.75, (height * 0.5) // 2 + y],
[x + width * 0.75, (height * 1.5) // 2 + y],
)
if count <= 0: # The base case
return
else: # The recursive step
count -= 1
recursivedraw(tur, x, y, width // 2, height // 2, count)
recursivedraw(tur, x + width // 2, y, width // 2, height // 2, count)
recursivedraw(tur, x, y + width // 2, width // 2, height // 2, count)
recursivedraw(tur, x + width // 2, y + width // 2, width // 2, height // 2, count)
if __name__ == "__main__":
screenset = turtle.Screen()
screenset.setup(screen_width, screen_height)
screenset.title(title)
screenset.bgcolor(bg_color)
artistpen = turtle.Turtle()
artistpen.hideturtle()
artistpen.pensize(pen_width)
artistpen.color(pen_color)
artistpen.speed(speed)
recursivedraw(artistpen, - drawing_width / 2, - drawing_height / 2, drawing_width, drawing_height, fractal_depth)
turtle.done()
```

**Output:**

In the following output, we can see that how recursion is working and making the same copies of a single picture.

## Fractal drawing turtle

In this section, we will learn about** how to draw fractal drawings** in python turtle.

Fractal is used to generate an infinite amount of copies of pictures that form a fractal pattern. This fractal drawing is drawn with the help of a turtle.

**Code:**

In the following code, we have imported the turtle library and after that, we have defined the** fractdraw() **later we use the** left() right() forward()** to give direction to the pattern.

```
from turtle import *
import turtle
def fractdraw(stp, rule, ang, dept, t):
if dept > 0:
x = lambda: fractdraw(stp, "a", ang, dept - 1, t)
y = lambda: fractdraw(stp, "b", ang, dept - 1, t)
left = lambda: t.left(ang)
right = lambda: t.right(ang)
forward = lambda: t.forward(stp)
if rule == "a":
left(); y(); forward(); right(); x(); forward(); x(); right(); forward(); y(); left();
if rule == "b":
right(); x(); forward(); left(); y(); forward(); y(); left(); forward(); x(); right();
turtle = turtle.Turtle()
turtle.speed(0)
fractdraw(5, "a", 90, 5, turtle)
```

**Output:**

In the following output, we can see how we draw the fractal turtle and how it is working to create the same picture multiple times using the fractal pattern.
