在Python中使用Turtle创建一个简单的动画

Turtle是一个类似于画板的Python功能，它可以让我们命令Turtle在上面画个不停我们可以使用像turtle.forward(…)和turtle.right(…)这样的函数，可以使Turtle移动。让我们创建一个基本的动画，让不同的小Turtle在为它们创建的轨道上比赛。

步骤

首先，导入所需的模块
在Turtle模块中有不同形状的指针（如箭头、经典和Turtle）。由于这是一场 “Turtle赛跑”，我们需要 “Turtle “和 “经典 “形状。
我们将使用经典的形状来绘制赛车道。
列出第一只Turtle的规格，将Turtle输入轨道，并将Turtle设置为比赛的准备。
对其余的Turtle也要这样做。
使用randint()来设置Turtle的速度。

以下是实现。

# required modules
from turtle import * from random import randint
  
     
# classic shape turtle
speed(0)
penup()
goto(-140, 140)
  
# racing track
 
for step in range(15):
    write(step, align ='center')
    right(90)
     
    for num in range(8):
        penup()
        forward(10)
        pendown()
        forward(10)
         
    penup()
    backward(160)
    left(90)
    forward(20)
 
# first player details
player_1 = Turtle()
player_1.color('red')
player_1.shape('turtle')
  
# first player proceeds to racing track
player_1.penup()
player_1.goto(-160, 100)
player_1.pendown()
  
# 360 degree turn
for turn in range(10):
    player_1.right(36)
 
# second player details
player_2 = Turtle()
player_2.color('blue')
player_2.shape('turtle')
  
# second player enters in the racing track
player_2.penup()
player_2.goto(-160, 70)
player_2.pendown()
  
# 360 degree turn
for turn in range(72):
    player_2.left(5)
 
# third player details
player_3 = Turtle()
player_3.shape('turtle')
player_3.color('green')
  
# third player enters in the racing track
player_3.penup()
player_3.goto(-160, 40)
player_3.pendown()
  
# 360 degree turn
for turn in range(60):
    player_3.right(6)
 
# fourth player details
player_4 = Turtle()
player_4.shape('turtle')
player_4.color('orange')
  
# fourth player enters in the racing track
player_4.penup()
player_4.goto(-160, 10)
player_4.pendown()
  
# 360 degree turn
for turn in range(30):
    player_4.left(12)
 
# turtles run at random speeds
for turn in range(100):
    player_1.forward(randint(1, 5))
    player_2.forward(randint(1, 5))
    player_3.forward(randint(1, 5))
    player_4.forward(randint(1, 5))
