这是雾化器改进后的答案。

注意2次update()调用和它们之间200ms的延迟。它们可以保护由于剪贴板状态不稳定而冻结的应用程序:

from Tkinter import Tk
import time     

r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append('some string')

r.update()
time.sleep(.2)
r.update()

r.destroy()

我在这里分享的代码片段利用了格式化文本文件的功能:如果您想将复杂的输出复制到剪贴板，该怎么办?(比如一个列中的numpy数组或一个列表)

import subprocess
import os

def cp2clip(clist):

    #create a temporary file
    fi=open("thisTextfileShouldNotExist.txt","w")

    #write in the text file the way you want your data to be
    for m in clist:
        fi.write(m+"\n")

    #close the file
    fi.close()

    #send "clip < file" to the shell
    cmd="clip < thisTextfileShouldNotExist.txt"
    w = subprocess.check_call(cmd,shell=True)

    #delete the temporary text file
    os.remove("thisTextfileShouldNotExist.txt")

    return w

只适用于windows，我猜可以适用于linux或mac。可能有点复杂……

例子:

>>>cp2clip(["ET","phone","home"])
>>>0

在任何文本编辑器中按Ctrl+V:

ET
phone
home

实际上，对于这个简单的任务，pywin32和ctypes似乎是多余的。tkinter是一个跨平台的GUI框架，默认情况下与Python一起发布，并具有剪贴板访问方法和其他很酷的东西。

如果你所需要的只是将一些文本放入系统剪贴板，这将做到:

from tkinter import Tk # in Python 2, use "Tkinter" instead 
r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append('i can has clipboardz?')
r.update() # now it stays on the clipboard after the window is closed
r.destroy()

仅此而已，不需要在特定于平台的第三方库上浪费时间。

如果您正在使用Python 2，请将tkinter替换为tkinter。

你也可以使用>剪贴板

import clipboard

def copy(txt):
    clipboard.copy(txt)
    
copy("your txt")

我认为有一个更简单的解决办法。

name = input('What is your name? ')
print('Hello %s' % (name) )

然后在命令行中运行程序

Python greeting .py |剪辑

这将把文件的输出输出到剪贴板

除了Mark Ransom使用ctypes的回答之外: 这并不适用于(所有?)x64系统，因为句柄似乎被截断为int-size。 显式定义参数和返回值有助于克服这个问题。
