Python Intensive

Day 4

Welcome! Today is November 1st, 2022.

Today's Agenda

4:30 - 4:45PM: Log on & Ice breakers: when did you get your first cell phone?

4:45 - 5:05PM: Definitions

Turtle: turtle is a pre-installed Python library that enables users to create pictures and shapes by providing them with a virtual canvas.
Global variable: Variables that are created outside of a function (as in all of the examples above) are known as global variables.
Friction: Friction is opposite to the direction of push applied on the body to make it move.

5:05 - 5:10 PM: Bio Break & Guided Python instruction

Python Intensive - Day 4 - Nov 1st 2022

Python Intensive [Day 4]

In this course, you will learn the basics of Python programming. We will meet every Tuesday at 4:30pm to 6:00pm. You don't need any previous programming experiences and all you need to code in Python is a web browser (www.replit.com). Mr. Steven will teach you all the core aspects of the Python programming and I will simplify the more complex topics.

Today we will be creating our simple python game!
- The goal is to create your game character and be able to move around the area. Next week we will add more features.

1. Import turtle & Setting up a canvas

import turtle

#setting up canvas

wn = turtle.Screen()

wn.bgcolor('black')

wn.title('TKU Python Game!')

2. Player Information

#setting up the player

player = turtle.Turtle()

player.speed(0)

player.penup()

# examples: green, blue, red

player.color('lime')

# examples: Square, Arrow, Circle, Turtle, Triangle, Classic

player.shape('turtle')

speed = 0

3. Arrow keys up,down,right,left & friction

#speed up forward

def speed_up():

global speed

speed += 2

if speed > 2:

speed = 2

#slow-down backward

def slow_down():

global speed

speed -= 2

if speed < -2:

speed = -2

def right():

player.rt(30) #rt means right

def left():

player.lt(30) #lt means left

#friction!

def friction():

global speed

player.friction = 0.97

speed *= player.friction

4. Key Configuration

#Now, we are going to configure with keys

turtle.listen()

turtle.onkeypress(speed_up, 'Up')

turtle.onkey(left, 'Left')

turtle.onkey(right, 'Right')

turtle.onkeypress(slow_down, 'Down')

5. Friction!

#friction

while True:

player.forward(speed)

friction()

6. Entire Code!

import turtle

#setting up canvas

wn = turtle.Screen()

wn.bgcolor('black')

wn.title('TKU Python Game!')

#setting up the player

player = turtle.Turtle()

player.speed(0)

player.penup()

# examples: green, blue, red

player.color('lime')

# examples: Square, Arrow, Circle, Turtle, Triangle, Classic

player.shape('turtle')

speed = 0

#speed up forward

def speed_up():

global speed

speed += 2

if speed > 2:

speed = 2

#slow-down backward

def slow_down():

global speed

speed -= 2

if speed < -2:

speed = -2

def right():

player.rt(30) #rt means right

def left():

player.lt(30) #lt means left

#friction!

def friction():

global speed

player.friction = 0.97

speed *= player.friction

#Now, we are going to configure with keys

turtle.listen()

turtle.onkeypress(speed_up, 'Up')

turtle.onkey(left, 'Left')

turtle.onkey(right, 'Right')

turtle.onkeypress(slow_down, 'Down')

#friction

while True:

player.forward(speed)

friction()
