解决Pycharm调用Turtle时 窗口一闪而过的问题

如下所示：

#彩色螺旋线

import turtle

turtle.pensize(2)

turtle.bgcolor("black")

colors = ["red","yellow","purple","blue"]

turtle.tracer(False)

for x in range(400):

turtle.forward(2*x)

turtle.color(colors[x % 4])

turtle.left(91)

turtle.tracer(True)

在用pycharm调用Turtle画图时，上面的代码显示一闪而过

最后加上一句turtle.done()即可解决

#彩色螺旋线

import turtle

turtle.pensize(2)

turtle.bgcolor("black")

colors = ["red","yellow","purple","blue"]

turtle.tracer(False)

for x in range(400):

turtle.forward(2*x)

turtle.color(colors[x % 4])

turtle.left(91)

turtle.tracer(True)

turtle.done()

效果如下：
