【问题描述】:
我一直在尝试使用goto() 将海龟发送到随机位置,但运行程序时出现错误。
我不知道如何做到这一点,并且不确定其他方式。 我当前的代码是:
t1.shape('turtle')
t1.penup()
t1.goto((randint(-100,0)),(randint(100,0)))#this is the line with the error
我希望海龟在 -100,100 和 0,100 之间的框中随机坐标,但出现错误:
Traceback (most recent call last):
File "C:\Users\samdu_000\OneDrive\Documents\python\battle turtles.py", line 18, in <module>
t1.goto((randint(-100,0)),(randint(100,0)))
File "C:\Users\samdu_000\AppData\Local\Programs\Python\Python3732\lib\random.py", line 222, in randint
return self.randrange(a, b+1)
File "C:\Users\samdu_000\AppData\Local\Programs\Python\Python37-
32\lib\random.py", line 200, in randrange
raise ValueError("empty range for randrange() (%d,%d, %d)" % (istart,
istop, width))
ValueError: empty range for randrange() (100,1, -99)
