How do I read text from the clipboard?

Question

You can use the module called win32clipboard, which is part of pywin32.

Here is an example that first sets the clipboard data then gets it:

import win32clipboard

# set clipboard data
win32clipboard.OpenClipboard()
win32clipboard.EmptyClipboard()
win32clipboard.SetClipboardText('testing 123')
win32clipboard.CloseClipboard()

# get clipboard data
win32clipboard.OpenClipboard()
data = win32clipboard.GetClipboardData()
win32clipboard.CloseClipboard()
print data

An important reminder from the documentation:

When the window has finished examining or changing the clipboard, close the clipboard by calling CloseClipboard. This enables other windows to access the clipboard. Do not place an object on the clipboard after calling CloseClipboard.

you can easily get this done through the built-in module Tkinter which is basically a GUI library. This code creates a blank widget to get the clipboard content from OS.

from tkinter import Tk  # Python 3
#from Tkinter import Tk # for Python 2.x
Tk().clipboard_get()

I found pyperclip to be the easiest way to get access to the clipboard from python:

1. Install pyperclip: pip install pyperclip

2. Usage:

import pyperclip
    
s = pyperclip.paste()
pyperclip.copy(s)
    
# the type of s is string

With supports Windows, Linux and Mac, and seems to work with non-ASCII characters, too. Tested characters include ±°©©αβγθΔΨΦåäö

I've seen many suggestions to use the win32 module, but Tkinter provides the shortest and easiest method I've seen, as in this post: How do I copy a string to the clipboard on Windows using Python?

Plus, Tkinter is in the python standard library.

If you don't want to install extra packages, ctypes can get the job done as well.

import ctypes

CF_TEXT = 1

kernel32 = ctypes.windll.kernel32
kernel32.GlobalLock.argtypes = [ctypes.c_void_p]
kernel32.GlobalLock.restype = ctypes.c_void_p
kernel32.GlobalUnlock.argtypes = [ctypes.c_void_p]
user32 = ctypes.windll.user32
user32.GetClipboardData.restype = ctypes.c_void_p

def get_clipboard_text():
    user32.OpenClipboard(0)
    try:
        if user32.IsClipboardFormatAvailable(CF_TEXT):
            data = user32.GetClipboardData(CF_TEXT)
            data_locked = kernel32.GlobalLock(data)
            text = ctypes.c_char_p(data_locked)
            value = text.value
            kernel32.GlobalUnlock(data_locked)
            return value
    finally:
        user32.CloseClipboard()

print(get_clipboard_text())
