关于#For in#的问题，如何解决？

>>> magicians=['alice','david','carolina']
>>> for magician in magicians:
... print(magician)
  File "<stdin>", line 2
    print(magician)
    ^
IndentationError: expected an indented block after 'for' statement on line 1
>>> 

你这是没缩进吧
for循环的下一行需要缩进的
改成：

magicians=['alice','david','carolina']
for magician in magicians:
    print(magician)
