打印空行? [英] Print empty line?

问题描述

我正在关注Python的初学者教程，这里有一个小练习，我必须添加一个额外的函数调用并在经文之间打印一行，如果我在函数调用之间打印一条空行，但如果我添加了该行，这会很好happyBirthday()末尾的空白打印行出现缩进错误，但是没有添加所有打印行都可以正常工作，有关为什么的任何建议?

I am following a beginners tutorial on Python, there is a small exercise where I have to add an extra function call and print a line between verses, this works fine if I print an empty line in between function calls but if I add an empty print line to the end of my happyBirthday() I get an indent error, without the added print line all works fine though, any suggestions as to why?

这是代码:

def happyBirthday(person):
    print("Happy Birthday to you!")
    print("Happy Birthday to you!")
    print("Happy Birthday, dear " + person + ".")
    print("Happy Birthday to you!")
    print("\n") #error line

happyBirthday('Emily')
happyBirthday('Andre')
happyBirthday('Maria')

推荐答案

只有在确实存在缩进错误的情况下，您才会始终得到缩进错误.仔细检查您的最后一行是否缩进与其他行相同-带有空格或制表符.最有可能的是，其中一些行带有空格(或制表符)，而另一行则带有制表符(或空格).

You will always only get an indent error if there is actually an indent error. Double check that your final line is indented the same was as the other lines -- either with spaces or with tabs. Most likely, some of the lines had spaces (or tabs) and the other line had tabs (or spaces).

信任错误消息-如果它说的是某些特定内容，请假定它是正确的，并找出原因.

Trust in the error message -- if it says something specific, assume it to be true and figure out why.
