秉着浪费时间就是浪费生命的原则，先说结论：

使用 pyperclip 库

python 与系统剪贴板的交互

python下有两个库可以实现这个功能：pyperclip 和 clipboard。两个库都是跨平台的剪贴板操作库，目前都可用（2022年4月10日）。

只不过，clipboard库年久失修，只提供了两个函数：copy()、paste()

pyperclip 还有人维护，提供的函数也更为多样。

使用示例

import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
text = pyperclip.paste()  # text will have the content of clipboard

import clipboard
clipboard.copy("abc")  # now the clipboard content will be string "abc"
text = clipboard.paste()  # text will have the content of clipboard

pyperclip其他常用函数

Pyperclip's documentation

pyperclip 的函数接口列表：

['copy', 'paste', 'waitForPaste', 'waitForNewPaste', 'set_clipboard', 'determine_clipboard']

pyperclip.waitForPaste(timeout=None)  # Doesn't return until non-empty text is on the clipboard.
pyperclip.waitForNewPaste(timeout=None)  # Doesn't return until the clipboard has something other than "original text".

使用过程中可能会遇到的问题： $\color{Red}{\text{Pyperclip could not find a copy/paste mechanism for your system. }}$

$\color{Green}{\text{解决方法}}$

sudo apt-get install xsel to install the xsel utility.

sudo apt-get install xclip to install the xclip utility.

pip install gtk to install the gtk Python module.

pip install PyQt4 to install the PyQt4 Python module.

其他不常用函数：

# Explicitly sets the clipboard mechanism. The "clipboard mechanism" is how the copy() and paste() functions interact with the operating system to implement the copy/paste feature. The clipboard parameter must be one of:pbcopy、pbobjc (default on Mac OS X)、gtk、qt、xclip、xsel、klipper、windows (default on Windows)、no (this is what is set when no clipboard mechanism can be found)
pyperclip.set_clipboard(clipboard_mechanism)
# Determine the OS/platform and set the copy() and paste() functions accordingly.
pyperclip.determine_clipboard()
