Python function to copy text to clipboard (so far only supports Windows).

cb.py

import sys
import subprocess

def copy(s):
    if sys.platform == 'win32' or sys.platform == 'cygwin':
        subprocess.Popen(['clip'], stdin=subprocess.PIPE).communicate(s)
    else:
        raise Exception('Platform not supported')

'''
# On Windows, with pywin32 installed, this can also be done like so:
import win32clipboard as cb
def copy(s):
    cb.OpenClipboard()
    cb.EmptyClipboard()
    cb.SetClipboardData(cb.CF_TEXT, str(s))
    cb.CloseClipboard()
'''

does it work for python 3.x with windows 64 bit

I was able to use python 3.6.5 using Windows 10 64 bit with this, but I had to add encoding='utf8' as an argument to Popen to pass strings to the function rather than a byte array.

I think you can also easily extend this to macOS using pbcopy in place of clip as well.

You might want to take a look (or contribute to) the pyperclip project, which does copy/paste functions for Windows/Mac/Linux.

Works perfectly fine on my Windows 10 64-bit and Python 3.8 64-bit, thanks.
