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

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，
