python - 改变 turtle 1's position changes turtle 2' 的位置

Question

def func():
    print("T POSITION: ", t.pos()) # prints 100, 100
    t2.pencolor("black")
    t2.setpos(0,0)
    print("T POSITION: ", t.pos()) # Now, prints 0, 0
    print("T2 POISTION: ", t2.pos())

两者皆有。 t.pos() 和 t2.pos() 设置为 (0,0) ，即使我声明为全局变量 t1 和t2 分别。

t= turtle.getturtle()
t.setpos(100,100)
t2 = turtle.getturtle().

如果我只想将t2的位置更改为0,0，我该如何完成此操作？

Answer 1

您需要copy.copy t2:

import turtle,copy
t= turtle.getturtle()
t.setpos(100,100)
t2 = copy.copy(turtle.getturtle())
def func():
    print("T POSITION: ", t.pos())
    t2.pencolor("black")
    t2.setpos(0,0)
    print("T POSITION: ", t.pos())
    print("T2 POISTION: ", t2.pos())
func()

现在你得到的结果是:

T POSITION:  (100.00,100.00)
T POSITION:  (100.00,100.00)
T2 POISTION:  (0.00,0.00)

否则:

>>> t==t2
True
>>> t is t2
True
>>> id(t)
333763277936
>>> id(t2)
333763277936
>>> id(t) == id(t2)
True
>>> 

它们是相同的对象!完全可以!
