我建议您可以使用 pyperclip，因为它与剪贴板相同，而且更新。

https://pypi.org/project/pyperclip/

import pyperclip
>>> pyperclip.copy('The text to be copied to the clipboard.')
>>> pyperclip.paste()
'The text to be copied to the clipboard.'

目前只处理明文。

在 Windows 上，不需要额外的模块。

在 Mac 上，此模块使用 pbcopy 和 pbpaste 命令，它们应该与 os.

在 Linux 上，此模块使用 xclip 或 xsel 命令，这些命令应与 os. 否则运行“sudo apt-get install xclip”或“sudo apt-get install xsel”（注意：xsel 似乎并不总是有效。）

否则在 Linux 上，您将需要安装 gtk 或 PyQt4 模块。

我希望这有帮助。 :)
