donow()task1()
Functions are a group of instructions
We define a function called task1()
Every indented 🫸 instruction is part of task1()

# Stay to the left!
task1()3. Challenge
def task1():
tina = turtle.Turtle()
tina.shape("turtle")
# Try changing the name
# What happens?
task2()I do👀👂
We create a 🐢 variable called tina
tina has a function called goto()
goto() moves tina to coordinates
def task1():
tina = turtle.Turtle()
tina.shape("turtle")
tina.goto(0,50)
tina.goto(50,0)
