14. Specify who the owner of the device is and sign in to Windows 10 with your Microsoft account.

15. Click Finish/Restart and remove the Windows Install Media

16. On restarting the system will run the new Windows operating system.

 

 

Steps to install Linux as a guest OS in Windows 10 OS using VMware.

 

1.    Download and Install the VMware Workstation Player and launch it.

2.    Create a VM by clicking “Create a New Virtual Machine”. Browse and select the Installer disc image file (iso) of Linux OS. Click Next

3.    In “Select a guest OS”, choose the guest OS (Linux) and its version. Click Next

4.    Under Specify Disk Capacity adjust Maximum disk size as required. Click Next and Confirm the selected size in next window.

5.    Click finish to add the Linux virtual machine to VMware Workstation Player.

6.    Open the VMware Workstation Player settings and customize the VM hardware as required.

7.    To launch the Linux virtual machine use the Play button in VMware Workstation Player.

File handling in Python has several functions for creating, reading, updating, and deleting files. Read - Default value. Opens a file for reading, error if the file does not exist. Append - Opens a file for appending, creates the file if it does not exist. Write - Opens a file for writing, creates the file if it does not exist. Create - Creates the specified file, returns an error if the file exists.

Pygame tool

PYGAME

 

Aim: To study about Pygame tool

 

Introduction to Pygame

Python is the most popular programming language and has vast libraries for various fields such as Machine Learning (Numpy, Pandas, Matplotlib), Artificial intelligence (Pytorch, TensorFlow), and Game development (Pygame, Pyglet).

Pygame was officially written by Pete Shinners. Pygame is a cross-platform set of Python modules designed for writing video games. Pygame adds functionality on top of the SDL library. Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. Pygame, together with SDL, allows users to create fully featured games and multimedia programs in the python language. Pygame is highly portable and runs on nearly every platform and operating system.

 

Pygame core modules

Pygame modules provide abstract access to specific hardware on user system, as well as uniform methods to work with that hardware. Important Pygame Modules include

cursors	load cursor images, includes standard cursors
display	control the display window or screen
draw	draw simple shapes onto a Surface
event	manage events and the event queue
font	create and render TrueType fonts
image	save and load images
joystick	manage joystick devices
key	manage the keyboard
mouse	manage the mouse
sndarray	manipulate sounds with numpy
surfarray	manipulate images with numpy
time	control timing
transform	scale, rotate, and flip images

 

 

General steps to creating a Pygame based program

1.    Importing and Initializing PyGame

1.    import the pygame library and initialize all the functions in the pygame modules. This allows pygame to connect its abstractions to user specific hardware.

2.    Setting Up the Display

1.    Create a screen / surface object on which the graphical operations will be performed.

3.    Draw objects / Load images on the surface object

4.    Create a clock and set the framerate

5.    Sound Effects

1.    pygame provides mixer to handle all sound-related activities. classes and methods in mixer provides background music and sound effects for various actions. music sub-module is used to stream individual sound files in a variety of formats.

6.    Using .blit() and .flip()

1.    blit stands for Block Transfer. blit is the process to render the game object onto the surface. The .blit() takes two arguments – The Surface to draw and the location (coordinates) at which to draw it on the source Surface.

2.    flip() updates the entire screen with everything that’s been drawn since the last flip.

7.    Setting Up the Game Loop – The game loop performs four very important functions:

1. Processing Events.
1. Process user input (Key presses, mouse movements, joystick movements) using the pygame event system.
2. All events in pygame are placed in the event queue, which can then be accessed and manipulated.
2. Updates the state of all game objects in response to the user input
3. Updates the display and audio output
4. Maintains the speed of the game
1. Every cycle of the game loop is called a frame. The number of frames handled each second is called the frame rate.
2. Frames continue to occur until some condition to exit the game is met. Example – The player closes the window.
7. Terminate the program.
