Python:字符串格式化程序以获得带下划线的标题

问题描述

为了构建我的控制台输出，我想打印一些信息，我想从一个带下划线的标题开始.但是如何在不创建额外变量的情况下很好地做到这一点?

To structure my console output, I want to print some information and I would like to start with an underlined headline.But how to do it nicely without creating an extra variable?

现在我是这样做的:

print("{:s}
{:s}
".format("This is an underlined headline.", len("This is an underlined headline.") * "-"))

什么给了我想要的输出:

what gives me the desired output:

This is an underlined headline.
-------------------------------

但是那个代码很糟糕.有没有更好的格式字符串来实现这一点?

But that code is bad. Is there some better format string to achieve that?

print("{0:s}
?????
".format("This is an underlined headline.", "-"))

谢谢:)

推荐答案

也许可以尝试使用 ANSI 转义序列

class Format:
    end = '33[0m'
    underline = '33[4m'

print(Format.underline + 'Your text here' + Format.end)

它将打印出带下划线的文本，对于整个 ANSI 转义序列文档，请单击这里
