BASIC  PYGAME  STARTING :-

import pygame
pygame.init()
screen = pygame.display.set_mode( (WIDTH,HEIGHT) )

---

BASIC REQUIRED CODE :-

There must be following code to get a screen

running = True
while running :
     for event in pygame.event.get():
         if event.type == QUIT:
            running = False
     pygame.display.update()

---

DRAWING WITH PYGAME

pygame.draw.rect(surface,(r,g,b),(x-coordinate,y-coordinate,width,height))

---

# Doing the same thing with pygame.Rect
rect = pygame.rect(x-coordinate,y-coordinate,width,height)
pygame.draw.rect(surface,(r,g,b),rect)

---

# RESIZING A RECTANGLE
rect.inflate(width , height) 
# if you give -ve width or height the rectangle 
# rectangle will become smaller and vice-versa


# ALSO NOTE THAT IF THE RECTANGLE IS ALREADY DRAWN 
# TO SEE THE CHANGE YOU NEED TO DRAW IT AGAIN

---

pygame.draw.circle(surface,(r,g,b),(x,y),radius,thickness)

---

MOUSE-RELATED STUFF :-

The following mouse functions can are there in pygame

mouse_x , mouse_y = pygame.mouse.get_pos() 
# GIVES MOUSE POSITION

---

DEALING WITH IMAGES :-

To add an image to your program :-

# LOADING THE IMAGE  -- 1st step without which 
# nothing else will work 
image = pygame.image.load(path_of_image)
# AN ADDITIONAL PARAMETER
image = pygame.image.load(path_of_image).convert_alpha()
# CHANGING IMAGE SIZE
image = pygame.transform.scale(image,(width,height))
# DRAWING THE IMAGE ON SCREEN
surface_or_screen.blit(image,(x,y))
