Draw Square and Rectangle in Turtle – Python

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 Turtle
import turtle

t = turtle.Turtle()

s = int(input("Enter the length of the side of the Square: "))

# drawing first side
t.forward(s) # Forward turtle by s units
t.left(90) # Turn turtle by 90 degree

# drawing second side
t.forward(s) # Forward turtle by s units
t.left(90) # Turn turtle by 90 degree

# drawing third side
t.forward(s) # Forward turtle by s units
t.left(90) # Turn turtle by 90 degree

# drawing fourth side
t.forward(s) # Forward turtle by s units
t.left(90) # Turn turtle by 90 degree

Input : 

100

Output :

Second approach (Using Loop) :

Python3

# draw Square in Python Turtle
import 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 Turtle
import turtle

t = turtle.Turtle()

l = int(input("Enter the length of the Rectangle: "))
w = int(input("Enter the width of the Rectangle: "))

# drawing first side
t.forward(l) # Forward turtle by l units
t.left(90) # Turn turtle by 90 degree

# drawing second side
t.forward(w) # Forward turtle by w units
t.left(90) # Turn turtle by 90 degree

# drawing third side
t.forward(l) # Forward turtle by l units
t.left(90) # Turn turtle by 90 degree

# drawing fourth side
t.forward(w) # Forward turtle by w units
t.left(90) # Turn turtle by 90 degree

Input :

100
120

Output :

Second approach (Using Loop) :

Python3

# draw Rectangle in Python Turtle
import 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 turtle

def 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 += 1


def 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 += 1


def draw_foot2(brad):
    brad.color("blue")
    num = 0
    while num < 4:
        brad.forward(20)
        brad.left(90)
        num += 1


draw_dream()
