places=["paris","lendon","shanghai"];for place in places:    print(place) #   we use indentation rather than brackets to present domainfor place in places:    print(place.title()+", this is the most beautiful place i hava seen")    print("i am waiting for the the next time to see you:"+place.title()+".\n"

Python中表示域，不用括号，而是缩进！！！！，因此上述代码中两个print均在for 语句的作用域中

单行注释用#

再次强调，缩进在Python中不可以乱用。不可以平白无故的使用缩进，使用缩进时一定要注意从属关系
