How make calculator in python We make a calculator in python using kivy module . Kivy module helps us to make android apps . First wait , If you run a kivy program in your terminal then you see a error like this To solve this problem you have to go kivy docs and follow the instruction of kivy docs. First we have to make a virtual environment and then in the virtual environment you have to install kivy . After that you have to write kivy_venv\Scripts\activate in your terminal and then run the file . If this method not work then write the comment below. LETS START CODING First we import kivy .For this we hve to write from kivy.app import App from kivy.uix.label import Label from kivy.uix.button import Button from kivy.core.window import Window from kivy.uix.gridlayout import GridLayout from kivy.uix.widget import Widget from kivy.lang import ...
How to make snake game in python
We make snake game in python with help of pygame module. pygame module helps in making games in python .
LETS START CODING
Import pygame and random
we have to import pygame and random module for making snake game. Random module helps to generate random position for food in the screen. for this we have to write
import pygame
import random
Creating game window
First we have to make game screen with the help of pygame. For this we have to write
screen_widht=460
screen_height=600
gameWindow=pygame.display.set_mode((screen_widht,screen_height))
pygame.display.set_caption("SNAKE GAME")
pygame.display.update()
Creating welcome screen
First we have to display welcome screen. For display screen we have to make a function . For this we have to write def welcome():
exit_game=False
while not exit_game:
gameWindow.fill((233,223,223))
# gameWindow.blit(home,(0,0))
textscreen("WELCOME TO SNAKES",red,33,33)
textscreen("PESS SPACE TO PLAY",red,33,66)
for event in pygame.event.get():
if event.type==pygame.QUIT:
exit_game=True
if event.type==pygame.KEYDOWN:
if event.key==pygame.K_SPACE:
gameloop()
pygame.display.update()
clock.tick(60)
Creating snake
After that we make a function which take gameWindow , color , snake length , snake width and plot the snake .For this we have to write
def plotsnake(gameWindow,color,snk_list,snake_size):
for x,y in snk_list:
pygame.draw.rect(gameWindow,color,[x,y,snake_size,snake_size])
NOTE - we take snk_list to increase the length of snake .
Moving the snake
After making the snake we have to move the snake . For this we use key event in the KEYDOWN class which is in pygame. We use K_UP , K_DOWN, K_LEFT , K_RIGHT to snake move up , down , left and right. After that we create velocity_x=0, velocity_y=0initvelocity=5
For make snake move we have to write
for event in pygame.event.get():
if event.type==pygame.QUIT:
exit_game=True
if event.type==pygame.KEYDOWN:
if event.key==pygame.K_RIGHT:
velocity_x=initvelocity
velocity_y=0
if event.key==pygame.K_LEFT:
velocity_x=-initvelocity
velocity_y=0
if event.key==pygame.K_DOWN:
velocity_y=initvelocity
velocity_x=0
if event.key==pygame.K_UP:
velocity_y=-initvelocity
velocity_x=0
snake_x = snake_x + velocity_x
snake_y = snake_y + velocity_y
Game over when snake hit the boundaries and itself
When snake hit the boundary and itself then game over and game over screen open and print the score . For this we have to write
if head in snk_list[:-1]:
game_over=True
if snake_x<0 or snake_x>screen_widht or snake_y<0 or snake_y>screen_height:
game_over=True
After game over a game over screen open where score are print
Adding food and score
For adding food we have to plot a rectangle in game screen. For this we have to write
pygame.draw.rect(gameWindow,foodcolor,[food_x,food_y,snake_size,snake_size])
When snake eat the food then add 10 score and also add snk_lenght which used to increase the size of snake . For this we have to write
if abs(snake_x-food_x)<10 and abs(snake_y-food_y)<10:
score += 10
food_x=random.randint(100,screen_widht-100)
food_y=random.randint(100,screen_height-100)
snakecolor=foodcolor
foodcolor=(random.randint(0,255),random.randint(0,255),random.randint(0,255))
snk_lenght+=5
Increasing the length of snake
To increase the length of snake, we have to make a list where then append position of snake in each frame in snk_list list . After that when snk_list more then snk_lenght , Then we delete the last element of list . For this we have to write
head.append(snake_x)
head.append(snake_y)
snk_list.append(head)
if len(snk_list)>snk_lenght:
del snk_list[0]
Game over screen
When snake hit the boundary and itself then game over window open and display the score . For this we have to write gameWindow.fill(white)
textscreen("GAME OVER",(255,55,55),5,5)
textscreen("PESS ENTER TO PLAY",(125,255,255),5,55)
textscreen("YOUR SCORE:"+str(score),(255,211,233),5,99)
for event in pygame.event.get():
if event.type==pygame.QUIT:
exit_game=True
if event.type==pygame.KEYDOWN:
if event.key==pygame.K_RETURN:
welcome()
Here text screen is a function . We use text screen function to display the text. For this we have to write
def textscreen(text,color,x,y):
screen_text=font.render(text,True,color)
gameWindow.blit(screen_text,[x,y])
HERE ARE THE CODE
OUTPUT
