Code:

import turtle import math import time screen = turtle.Screen() screen.setup(700, 700) screen.bgcolor("#02020a") screen.tracer(0) t = turtle.Turtle() t.hideturtle() t.speed(0) t.width(2) colors = [ "#ff1744", "#ff4081", "#d500f9", "#7c4dff", "#00e5ff", "#00ff9d" ] # 🌸 Lotus petals for layer in range(13): t.color(colors[layer % len(colors)]) size = 55 + layer * 11 for petal in range(12): rotation = petal * 30 + layer * 2 t.penup() for i in range(81): a = math.radians(i * 4.5) # Smooth pointed petal r = size * math.sin(a) r *= 0.75 + 0.25 * math.sin(a * 2) x = r * math.cos(a) y = r * math.sin(a) rot = math.radians(rotation) X = x * math.cos(rot) - y * math.sin(rot) Y = x * math.sin(rot) + y * math.cos(rot) t.goto(X, Y) if i == 0: t.pendown() screen.update() time.sleep(0.012) time.sleep(0.08) # ✨ Sparkling center for r in range(40, 2, -2): t.penup() t.goto(0, -r) t.dot(r, colors[r % len(colors)]) screen.update() time.sleep(0.08) t.penup() t.goto(0, -6) t.dot(12, "white") turtle.done()

Explanation:

1. Import Libraries

import turtleimport mathimport time

- turtle → draws the lotus flower.

- math → performs mathematical and trigonometric calculations.

- time → controls animation speed.

2. Create the Screen

screen = turtle.Screen()screen.setup(700, 700)screen.bgcolor("#02020a")screen.tracer(0)

- Creates a 700 × 700 drawing window.

- Sets a dark background.

- tracer(0) disables automatic screen updates.

3. Configure the Turtle

t = turtle.Turtle()t.hideturtle()t.speed(0)t.width(2)

- Creates the drawing turtle.

- Hides the turtle cursor.

- speed(0) sets maximum drawing speed.

- width(2) sets the line thickness.

4. Define Neon Colors

colors = [    "#ff1744", "#ff4081",    "#d500f9", "#7c4dff",    "#00e5ff", "#00ff9d"]

- Stores six neon colors.

- The colors repeat across the lotus layers.

5. Create Lotus Layers

for layer in range(13):

- Creates 13 layers of petals.

- Each layer uses a different size and rotation.

6. Select the Layer Color

t.color(colors[layer % len(colors)])

- Selects a color for the current layer.

- The modulo operator % repeats the colors when needed.

7. Calculate Petal Size

size = 55 + layer * 11

- Starts with a size of 55.

- Increases the size by 11 for each new layer.

- Creates an expanding lotus effect.

8. Create 12 Petals

for petal in range(12):

- Generates 12 petal curves in each layer.

9. Calculate Petal Rotation

rotation = petal * 30 + layer * 2

- petal * 30 separates 12 petals evenly around 360°.

- layer * 2 slightly rotates each new layer.

10. Lift the Pen

t.penup()

- Prevents unwanted lines when moving to the starting position.

11. Generate Petal Points

for i in range(81):

- Generates 81 points for each petal curve.

- More points help create a smooth shape.

12. Calculate the Angle

a = math.radians(i * 4.5)

- Converts degrees into radians.

- The angle progresses from 0° to 360°.

13. Create the Petal Radius

r = size * math.sin(a)

- Calculates the distance from the center.

- The sine function helps form the pointed petal shape.

14. Smooth the Petal Shape

r *= 0.75 + 0.25 * math.sin(a * 2)

- Modifies the radius using another sine wave.

- Adds a smooth, curved appearance to the petals.

15. Calculate X Coordinate

x = r * math.cos(a)

- Calculates the horizontal position of the point.

16. Calculate Y Coordinate

y = r * math.sin(a)

- Calculates the vertical position.

- Together, x and y create the petal curve.

17. Convert the Rotation Angle

rot = math.radians(rotation)

- Converts the petal's rotation angle into radians.

18. Rotate the X Coordinate

X = x * math.cos(rot) - y * math.sin(rot)

- Calculates the rotated horizontal position.

19. Rotate the Y Coordinate

Y = x * math.sin(rot) + y * math.cos(rot)

- Calculates the rotated vertical position.

- Together, these formulas rotate each petal around the center.

20. Move to the Calculated Point

t.goto(X, Y)

- Moves the turtle to the new coordinates.

21. Start Drawing the Petal

if i == 0:    t.pendown()

- Lowers the pen at the first point.

- The following points are connected to draw the curve.

22. Animate the Petals

screen.update()time.sleep(0.012)

- Refreshes the screen.

- Adds a short delay to show the drawing animation.

23. Pause Between Petals

time.sleep(0.08)

- Adds a small pause after each petal.

- Makes the drawing process easier to watch.

24. Create the Sparkling Center

for r in range(40, 2, -2):

- Creates circles with decreasing sizes.

- The radius decreases from 40 to 4.

t.penup()t.goto(0, -r)t.dot(r, colors[r % len(colors)])

- Moves to the center area.

- Draws colorful dots of different sizes.

- Produces a layered, sparkling center.

25. Animate the Center Glow

screen.update()time.sleep(0.08)

- Updates the screen after each circle.

- Creates a gradual glowing effect.

26. Add the White Core

t.penup()t.goto(0, -6)t.dot(12, "white")

- Adds a white dot in the center.

- Creates a bright highlight.

27. Finish the Drawing

turtle.done()

- Keeps the Turtle graphics window open.
