但错就错在,列表中应该存放函数名,而不是直接function() 加了括号,那就直接调用了,换句话说,我之前的函数都没有返回值,那列表中就是很多个空值,调用出来也没什么效果,自然无法填充,函数名不加括号(),才代表的是这个函数,加括号就是执行这个函数!!! 最终改动代码如下: importturtleastimportmathimportrandom t....
下面我们举一个带返回值的函数的例子:def even_list(n): lst = [] for i in range(0, n, 2): l.append(i) return lsttest_list = even_list(10)print(test_list)这个函数可以生成一个由偶数组成的列表,返回值是一个列表。调用函数时,可以使用变量获取函数的返回值。五、函数参数的默...
但我不确定)如果我们的目标是使用 turtle 绘制一个简单的线函数,我们可以更简单:from turtle import ...

我们先从常规的方式从入口开始探究turtle库的基本实现;新建一个turtle对象: tt=Turtle() 1. 在文件中找到 class Turtle: class Turtle(RawTurtle): """RawTurtle auto-creating (scrolled) canvas. When a Turtle object is created or a function derived from some ...

In this section, we will learn abouthow to create a random functionin python turtle. Before moving forward we should have a piece of knowledge aboutrandom function. MY LATEST VIDEOS Randomis defined as an action that is happening without any method or we can say that it is unfamiliar or un...
The turtle clear function is also used to remove the drawing that the user draws on the screen and remain the turtle as it is. Code: In the following code, we will import the turtle modulefrom turtle import *,import turtle as tur. theturtle()method is used to make objects. ...
