python - 使用格式说明符的 Python 中心字符串

Question

我有一个名为message.

message = "Hello, welcome!\nThis is some text that should be centered!"

我正在尝试使用以下语句将其置于默认终端窗口的中心，即 80 宽度：

print('{:^80}'.format(message))

哪个打印：

           Hello, welcome!
This is some text that should be centered!           

我期待类似的东西：

                                Hello, welcome!                                 
                   This is some text that should be centered!                   

有什么建议么？

Answer 1

您需要将每条线分别居中：

'\n'.join('{:^80}'.format(s) for s in message.split('\n'))

Answer 2

这是一个替代方案，它将根据最长宽度自动居中您的文本。

def centerify(text, width=-1):
  lines = text.split('\n')
  width = max(map(len, lines)) if width == -1 else width
  return '\n'.join(line.center(width) for line in lines)

print(centerify("Hello, welcome!\nThis is some text that should be centered!"))
print(centerify("Hello, welcome!\nThis is some text that should be centered!", 80))
