python - 如何打印 FF(换页)字符？

Question

我做了一些旧报表转换，需要添加“新页”FF 字符。从 Python 打印 FF 字符的语法是什么？

Answer 1

赞this *Wikipedia article说 Form Feed (FF) 在 ASCII 中有十进制值 12。这是十六进制的 0x0c:

Form feed is a page-breaking ASCII control character. It forces the printer to eject the current page and to continue printing at the top of another. Often, it will also cause a carriage return. The form feed character code is defined as 12 (0xC in hexadecimal) (..) In the C programming language (and other languages derived from C), the form feed character is represented as '\f'.

所以你可以:

print('\x0c',end='')

或者你可以使用 - like @martineau says - 使用 '\f':

print('\f',end='')

end='' 用于防止 Python 在换页符后打印额外的新行。

请注意，这取决于控制台(或接收流的设备)如何处理换页。一些控制台可能会忽略它。其他人打印一些空行，例如，打印机可能决定开始一个新页面。
