turtle.speed() 是 Python turtle 库中的一个函数,用于设置 turtle 绘图时的速度。这个函数可以传入一个参数,表示速度等级,取值范围为 0 到 10,其中 0 表示最慢,10 表示最快。如果不传入参数,函数会返回当前的速度等级。例如,可以使用以下代码将 turtle 的速度设置为 5:
```
import turtle
turtle.speed(5)
```
或者使用以下代码获取当前 turtle 的速度等级:
```
import turtle
speed_level = turtle.speed()
print(speed_level)
```

修改代码使图中的小圆绕大圆圈的圆心以200圈每秒的速度进行圆周运动:import turtle import math # Set up the turtle screen screen = turtle.Screen() screen.bgcolor("white") screen.title("Circle with Moving Black Dot") # Create the turtle for drawing the circle circle_turtle = turtle.Turtle() circle_turtle.speed(0) circle_turtle.hideturtle() circle_turtle.penup() circle_turtle.goto(0, -80) circle_turtle.pendown() circle_turtle.color("black") circle_turtle.circle(80, 2880) # Create the turtle for drawing the black dot dot_turtle = turtle.Turtle() dot_turtle.speed(0) dot_turtle.hideturtle() dot_turtle.penup() dot_turtle.goto(40, 0) dot_turtle.pendown() dot_turtle.color("black") dot_turtle.begin_fill() dot_turtle.circle(4) dot_turtle.end_fill() # Calculate the angle increment for each frame of animation angle_increment = 1 / 60 # 200 degrees per second, 60 frames per second # Animate the movement of the black dot while True: dot_turtle.clear() angle = dot_turtle.heading() + angle_increment x = 40 * math.cos(math.radians(angle)) y = 40 * math.sin(math.radians(angle)) dot_turtle.goto(x, y) dot_turtle.begin_fill() dot_turtle.circle(6) # 小圆 dot_turtle.end_fill()
可以使用Python的time模块来控制圆周运动的速度,修改代码如下:
```python
import turtle
import math
import time
# Set up the turtle screen
screen = turtle.Screen()
screen.bgcolor("white")
screen.title("Circle with Moving Black Dot")
# Create the turtle for drawing the circle
circle_turtle = turtle.Turtle()
circle_turtle.speed(0)
circle_turtle.hideturtle()
circle_turtle.penup()
circle_turtle.goto(0, -80)
circle_turtle.pendown()
circle_turtle.color("black")
circle_turtle.circle(80, 2880)
# Create the turtle for drawing the black dot
dot_turtle = turtle.Turtle()
dot_turtle.speed(0)
dot_turtle.hideturtle()
dot_turtle.penup()
dot_turtle.goto(40, 0)
dot_turtle.pendown()
dot_turtle.color("black")
dot_turtle.begin_fill()
dot_turtle.circle(4)
dot_turtle.end_fill()
# Calculate the angle increment for each frame of animation
angle_increment = 200 / 60 # 200 degrees per second, 60 frames per second
# Animate the movement of the black dot
while True:
dot_turtle.clear()
angle = dot_turtle.heading() + angle_increment
x = 80 * math.cos(math.radians(angle))
y = 80 * math.sin(math.radians(angle))
dot_turtle.goto(x, y)
dot_turtle.begin_fill()
dot_turtle.circle(6) # 小圆
dot_turtle.end_fill()
time.sleep(1/60) # 控制运动速度
```
在上面的代码中,我们使用了time.sleep()函数来控制小圆的运动速度,将每帧的时间间隔设置为1/60秒。这样,小圆每秒绕大圆圈转200圈,同时每秒刷新60次界面,就可以实现流畅的圆周运动。
turtle.speed(1)
turtle.speed(1) 是一个 Python turtle 模块的函数,用于设置乌龟绘图的速度。速度的范围是 0-10,其中 0 表示最快,10 表示最慢。当你调用 turtle.speed(1) 时,它会将速度设置为 1,也就是第二慢的速度。如果你需要更快或更慢的速度,可以尝试其他参数。例如,turtle.speed(0) 将设置速度为最快。
