Snake game using turtle in python

#Snake game using turtle in python #Step 1: We will be importing modules into the program and giving default values for the game. import turtle import time import random delay = 0.1 score = 0 high_score = 0 #Step 2: Now, we will be creating the display of the game, i.e, the window screen for the game where we will create the head of the snake and food for the snake in the game and displaying the scores at the header of the game. # Creating a window screen wn = turtle.Screen() wn.title("Snake Game") wn.bgcolor("blue") # the width and height can be put as user's choice wn.setup(width=600, height=600) wn.tracer(0) # head of the snake head = turtle.Turtle() head.shape("square") head.color("white") head.penup() head.goto(0, 0) head.direction = "Stop" # food in the game food = turtle.Turtle() colors = random.choice(['red', 'green', 'black']) shapes = random.choice(['square', 'triangle', 'circle']) food.speed(0) food.shape(shapes) food.color(colors) food.penup() food.goto(0, 100) pen = turtle.Turtle() pen.speed(0) pen.shape("square") pen.color("white") pen.penup() pen.hideturtle() pen.goto(0, 250) pen.write("Score : 0 High Score : 0", align="center", font=("candara", 24, "bold")) #Step 3: Now, we will be validating the key for the snake’s movements.
