for magician in magicians:

    print(magician.title() + ",that was a great trick!")
   
    print("I can't wait to see your next trick," + magician.title() + ".\n")
为什么不能打印

不懂

书上的一段代码
magicians = ['alice','david','carolina']
for magician in magicians:
    print(magician.title() + ",that was a great trick!")
    print("I can't wait to see your  next trick," + magickan.title() + ".\n")
 打印运行时失败。不知道哪儿出了问题。

问题解决了，是因为第4行总写成了第3行的子代码了，

为什么下载好了Python,也可以正常使用，但是保存了程序就打不开了，该怎么办呢？求大家救救孩子

import turtle
turtle.pensize(2)
turtle.circle(10)
turtle.circle(40)
turtle.circle(80)
turtle.circle(160)

没有问题，就是不能运行
