Python:字符串格式化程序获得带下划线的标题 [英] Python: String formatter to get underlined headline

问题描述

要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呢?

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?

现在我这样做:

print("{:s}\n{:s}\n".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.
-------------------------------

但是该代码是错误的.有没有更好的格式字符串可以实现这一目标?

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

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

谢谢:)

推荐答案

也许尝试使用 ANSI转义序列

class Format:
    end = '\033[0m'
    underline = '\033[4m'

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

它将打印带下划线的文本，有关整个ANSI转义序列文档，请单击此处
