Introduction
To draw Cat using Python Turtle, we will utilize the turtle package. It is a Python GUI package that can be used to draw anything, including characters, cartoons, shapes, and other objects.
If you’re new to Python, drawing a cat can be tricky, but don’t worry, I’ll explain everything and supply you with the code for this application.
More articles about the python turtle and its projects can be found on our website. You can use our website’s search box or go to our Homepage.
Steps of Creating Cat using Python Turtle :
Step 1: Import The Turtle and Math Library
import turtle
import math
Step 2: Select the Background Color
window = turtle.Screen()
window.bgcolor("yellow")
#Bg color is use to set the background color
Step 3: Declare the Cursor Size and Speed
cursor = turtle.Turtle() # Cursor
cursor.shape("turtle")
cursor.color("black")
cursor.speed(3)
cursor.pensize(10)
Step 4: Create a Function to set X and Y Position
def movePen(cursor, x, y):
cursor.penup()
#Penup() ensures that the moving object you've created does not draw anything on the window.
cursor.setposition(x, y)
#setpos (also can be used as .setposition()) can be used to set a position for turtle.
cursor.pendown()
#pendown() tell the turtle to leave ink on the screen as it moves or not to leave ink.
def movePenX(cursor, x):
cursor.penup()
cursor.setx(x)
#setx() can be used to change the turtle’s positing along the x-axis (horizontally) while vertical position is untouched.
cursor.pendown()
def movePenY(cursor, y):
cursor.penup()
cursor.sety(y)
cursor.pendown()
def positionAlongCircle(x, y, radius, angle):
radians = math.radians(angle)
return [x + (radius*math.sin(radians)),
y + (radius*math.cos(radians))]
#This function is use for to draw ears whiskers around the circle
Step 5: Draw the head
movePenY(cursor, -150)
cursor.circle(150)
Step 6: Draw the Nose
noseMouthOffset = -15
movePenY(cursor, -20 + noseMouthOffset)
cursor.circle(20)
Step 7: Draw the mouth
movePen(cursor, -100, -20 + noseMouthOffset)
cursor.right(90)
cursor.circle(50, 180)
cursor.left(180)
cursor.circle(50, 180)
Step 8: Draw the eyes
eyeSpacingX = 30
eyePosY = 40
eyeRadius = 30
Step 9: Right eye
movePen(cursor, eyeSpacingX, eyePosY)
cursor.right(180)
cursor.circle(eyeRadius, -180)
Step 10: Left eye
movePen(cursor, -eyeSpacingX, eyePosY)
cursor.circle(eyeRadius, 180)
Step 11: Draw the tongue
movePen(cursor, -20, -60 + noseMouthOffset)
cursor.circle(20, 180)
Step 12: Draw the ears
# Right ear
earBeginAngle = 25
earSize = 85
earWidth = 22
positionA = (0, 0, 150, earBeginAngle)
movePen(cursor, positionA[0], positionA[1])
positionB = positionAlongCircle(0, 0, 150 + earSize, earBeginAngle + earWidth)
cursor.setposition(positionB[0], positionB[1])
positionC = positionAlongCircle(0, 0, 150, earBeginAngle + earWidth * 2)
cursor.setposition(positionC[0], positionC[1])
# Left ear
positionA = positionAlongCircle(0, 0, 150, -earBeginAngle)
movePen(cursor, positionA[0], positionA[1])
positionB = positionAlongCircle(0, 0, 150 + earSize, -earBeginAngle + -earWidth)
cursor.setposition(positionB[0], positionB[1])
positionC = positionAlongCircle(0, 0, 150, -earBeginAngle + -earWidth * 2)
cursor.setposition(positionC[0], positionC[1])
Step 13: Draw the Whiskers
whiskerLength = 180
# Right whiskers
movePen(cursor, 50, -15)
cursor.setheading(0)
cursor.forward(whiskerLength)
movePen(cursor, 50, 0)
cursor.left(5)
cursor.forward(whiskerLength)
# Left whiskers
movePen(cursor, -50, -15)
cursor.setheading(180)
cursor.forward(whiskerLength)
movePen(cursor, -50, 0)
cursor.left(-5)
cursor.forward(whiskerLength)
window.exitonclick()
#exitonclick() was created to end program.
