# Lesson Learns

# Function

Basically, function is a group of command.

main.py

from turtle import *

my_turtle = Turtle()
my_turtle.shape("turtle")

my_turtle.forward(50)
my_turtle.left(90)
my_turtle.forward(50)
my_turtle.left(90)

As you can see code line 6-13. They are creating a rectangle. We can make it into one group.

output

main.py

from turtle import *

my_turtle = Turtle()
my_turtle.shape("turtle")

def rect():
    my_turtle.forward(50)
    my_turtle.left(90)
    my_turtle.forward(50)
    my_turtle.left(90)
    my_turtle.forward(50)
    my_turtle.left(90)
    my_turtle.forward(50)

from turtle import *

my_turtle = Turtle()
my_turtle.shape("turtle")

def rect():
    for i in range(4):
      my_turtle.forward(50)
      my_turtle.left(90)


rect()
my_turtle.forward(50)
