Prerequisite: Turtle Programming Basics
turtle is an inbuilt module in Python. It provides drawing using a screen (cardboard) and turtle (pen). To draw something on the screen, we need to move the turtle (pen). To move turtle, there are some functions i.e forward(), backward(), etc.
Drawing Square:
Python3
# draw square in Python Turtleimport turtle t = turtle.Turtle()s = int(input("Enter the length of the side of the Square: "))# drawing first sidet.forward(s) # Forward turtle by s unitst.left(90) # Turn turtle by 90 degree# drawing second sidet.forward(s) # Forward turtle by s unitst.left(90) # Turn turtle by 90 degree# drawing third sidet.forward(s) # Forward turtle by s unitst.left(90) # Turn turtle by 90 degree# drawing fourth sidet.forward(s) # Forward turtle by s unitst.left(90) # Turn turtle by 90 degree |
Input :
100
Output :
Second approach (Using Loop) :
Python3
# draw Square in Python Turtleimport turtle t = turtle.Turtle()s = int(input("Enter the length of the side of square: "))for _ in range(4): t.forward(s) # Forward turtle by s units t.left(90) # Turn turtle by 90 degree |
Input :
100
Output :
Drawing Rectangle:
Python3
# draw Rectangle in Python Turtleimport turtle t = turtle.Turtle()l = int(input("Enter the length of the Rectangle: "))w = int(input("Enter the width of the Rectangle: "))# drawing first sidet.forward(l) # Forward turtle by l unitst.left(90) # Turn turtle by 90 degree# drawing second sidet.forward(w) # Forward turtle by w unitst.left(90) # Turn turtle by 90 degree# drawing third sidet.forward(l) # Forward turtle by l unitst.left(90) # Turn turtle by 90 degree# drawing fourth sidet.forward(w) # Forward turtle by w unitst.left(90) # Turn turtle by 90 degree |
Input :
100 120
Output :
Second approach (Using Loop) :
Python3
# draw Rectangle in Python Turtleimport turtle t = turtle.Turtle()l = int(input("Enter the length of the Rectangle: "))w = int(input("Enter the width of the Rectangle: "))for _ in range(4): # drawing length if _% 2 == 0: t.forward(l) # Forward turtle by l units t.left(90) # Turn turtle by 90 degree # drawing width else: t.forward(w) # Forward turtle by w units t.left(90) # Turn turtle by 90 degree |
Input :
100 120
Output :
Since as of now, you must have learned how to draw various basic geometrical illustrations like circle, square, rectangle. So, let’s implement this knowledge to build something which you can really use in building games like let’s draw a human being using the basic knowledge of geometrical knowledge.
Here the code for this implementation:-
Python3
import turtledef draw_dream(): window = turtle.Screen() window.bgcolor("white") draw_Scarlett() window.exitonclick()def draw_Scarlett(): brad = turtle.Turtle() brad.shape("turtle") brad.color("red") draw_head(brad) draw_body(brad) draw_arm(brad) draw_leg1(brad) draw_leg2(brad)def draw_head(brad): brad.circle(60) brad.speed(3) brad.right(60)def draw_body(brad): num = 0 while num < 3: brad.forward(150) brad.right(120) brad.speed(1) num += 1def draw_arm(brad): brad.forward(60) brad.left(60) brad.forward(60) brad.backward(60) brad.right(60) brad.backward(60) brad.right(60) brad.forward(60) brad.right(60) brad.forward(60) brad.backward(60) brad.left(60) brad.forward(90)def draw_leg1(brad): brad.left(120) brad.forward(40) brad.right(120) brad.forward(120) draw_foot1(brad)def draw_leg2(brad): brad.color("red") brad.right(180) brad.forward(120) brad.right(60) brad.forward(70) brad.right(60) brad.forward(120) draw_foot2(brad)def draw_foot1(brad): brad.color("blue") num = 0 while num < 4: brad.forward(20) brad.right(90) num += 1def draw_foot2(brad): brad.color("blue") num = 0 while num < 4: brad.forward(20) brad.left(90) num += 1draw_dream() |
