python的新功能。我正在尝试学习python中的turtle模块,但无法设置它。这是我要运行的脚本:
import turtle
bob = turtle.Turtle()
print(bob)
turtle.mainloop()
bob.fd(1000)
这是我得到的错误:
Traceback (most recent call last):
File "turtle_test.py", line 6, in <module>
bob.fd(1000)
File "/usr/lib/python3.6/turtle.py", line 1637, in forward
self._go(distance)
File "/usr/lib/python3.6/turtle.py", line 1605, in _go
self._goto(ende)
File "/usr/lib/python3.6/turtle.py", line 3158, in _goto
screen._pointlist(self.currentLineItem),
File "/usr/lib/python3.6/turtle.py", line 755, in _pointlist
cl = self.cv.coords(item)
File "<string>", line 1, in coords
File "/usr/lib/python3.6/tkinter/__init__.py", line 2466, in coords
self.tk.call((self._w, 'coords') + args))]
_tkinter.TclError: invalid command name ".!canvas"
如果有什么可以帮助我指出我做错了的事情,将不胜感激。
答案 0 :(得分:0)
您只是按错误的顺序排列了行:
import turtle
bob = turtle.Turtle()
print(bob)
bob.fd(1000)
turtle.mainloop()
最后的turtle.mainloop()
行将控制权移交给tkinter的事件循环,因此之后的任何行直到窗口关闭且乌龟环境被拆除之前都不会执行。即这通常是您在乌龟程序中要做的最后一件事。
