FOR PREPERATION & REFERENCE

Prerequisites

FOR STUDENTS

Computer with Internet connection.
Spyder IDE installed.
"pygame" package installed.

FOR TEACHER

Computer with Internet connection.
Latest browser installed.
"pygame" package installed.
Spyder IDE installed.

Which of the following options is associated with objects?

A

State

Behaviour

Output

Q.1 B

C

D

State and Behaviour

We learned in "Bullet Firing" class that when an object changes its position, its "State and Behavior" changes. So the correct answer is D.

Which function is used to set the equal frequency of the frames?

A

C

B

frame()

time()

tick()

Q.2 C

tick()

The "tick()" function is used to set the frame/ second in the game. You can use this like "clock.tick(30)", where a clock is an object created by "time.Clock()".

D

clock()

Today, we are going to learn:

1. Concept of Object-Oriented Programming.

2. Dictionary in python.

3. Game creation by applying OOP's.

Concepts in Object Oriented Programming

Constructor

Encapsulation

Objects

Classes

In a car manufacturing company, an engineer creates the blueprint of a car

OBJECTS

CLASS

Encapsulation

It is the process of binding properties with methods.

Here, in this example, we bound the property "Stop" with "Break()", "Speed" with "accelerator()", and "Fuel consumption" with "Engine".

Stop

Break()

Speed

accelerator()

Properties

Method

Fuel consumption

Engine()

Syntax for classes in Python

class <ClassName>:
  
  variableName1,variableName2
  
   def fun1(self):
      ______________
      ______________
      ______________
   
   def fun2(self):
      _____________
      _____________
      _____________

class Car:
    
    engineCapacity=10
    maxSpeed=200

    def enginepower(self):
        print('Engine Capacity is ',self.engineCapacity)

    def accelerator(self):
         print("Maximum speed of Car",self.maxSpeed)

mycar=Car()

mycar.enginepower()

mycar.accelerator()

Teacher Activity 1: Create a Class and its object

Output

Importance of "self" keyword in object-oriented programming

class car:

    def car_color(self,color):

        self.color=color

    def car_cost(self,cost):

        self.cost=cost

    def car_speed(self,speed):

        self.speed=speed

Sports Car:

Green color
$Y
500 Kph

Van Car:

White color
$X
100 Kph

Role of a "constructor" in a python class

Default interior

customized interior

In Python and any other object-oriented programming language, the role of a constructor is to assign values to instances of variables that the object will need whenever it starts.

Syntax of a Constructor in python

class <name_of_the_class>:
    
    <variable_name_1>=_____________
    <variable_name_2>=_____________

    def __init__(self,<variable_name_1>,<variable_name_2>):
        self.<variable_name_1>=<variable_name_1>
        self.<variable_name_2>=<variable_name_2>
        
    def <function_1>(self):
       _____________________

    def <function_2>(self):
       _____________________

Teacher Activity 2: Constructor in python

class Car:
    
    engineCapacity=10
    maxSpeed=200

    def __init__(self,capacity,speed):
        self.engineCapacity=capacity
        self.maxSpeed=speed
        
    def enginepower(self):
        print('Engine Capacity is ',self.engineCapacity)

    def accelerator(self):
         print("Maximum speed of Car",self.maxSpeed)

mycar=Car(30,150)

mycar.enginepower()

mycar.accelerator()

Creating the game screen

Import pygame
Initialize pygame
Create the screen
Set screen caption
Create the game loop
Finish the game

init()

import

display.set_mode()

display.set_caption()

while True:

pygame.quit()

Steps to be followed:

Let's begin by creating the basic game screen.

Output for Teacher Activity 3

GREAT!

John is trying to understand meaning of the phrase, "stroke of genius". Suggest him from where he can get the correct meaning of this phrase.

Syntax for Dictionary in Python

<name_of_dictionary> = {'<key1>': '<value1>', '<key2>': <value2>}

print(<name_of_dictionary>['<value1>'])

print(<name_of_dictionary>.get('<value2>'))

Built-in data type in Python.

It is an ordered collection of data-values

Dictionary holds "key:value" pairs

images={}
images["bg1"] = pygame.image.load("D:/Flappy for AI/bg1.png").convert_alpha()
images["base"] = pygame.image.load("D:/Flappy for AI/base.png").convert_alpha()

Teacher Activity 4 solution: https://bit.ly/3xTR8kp

Output Teacher Activity-4

Student Activity-1: Adding an image of flappy bird to the game window using a dictionary

Hints:

Create an entry into the dictionary for flapy bird's image

use screen.blit() function, to position the flappy bird image at (100,250)

Template link: https://bit.ly/2V1i9na

Which of the following is valid symbol for dictionary in python?

Q.1 A

B

[]

A

The correct answer is option A

C

D

my_dictionary = {'name': 'Martin', 'age': 16}

my_dictionary = ['name': 'Martin', 'age': 16]

my_dictionary = "'name': 'Martin', 'age': 16"

my_dictionary = ('name': 'Martin', 'age': 16)

What would be the output of the following code:

Q.2 A

C

B

10 10 20

"John":10

D

Error in code.

A

10

dictionary_name={"John": 10, "maria":20}
print(dictionary_name["John"])

The correct answer is A.
The print() statement is used to print the value which is stored in the key named "John"
