No, but I use pyperclip.  It's cross platform.  Maybe it doesn't have this 
problem, though I don't know for sure.

It also happens in Python 3.10, but not Python 3.9.

Writing to clipboard in Python 3.11

2023-11-07 Thread Rob Cliffe via Python-list 
Recently I switched from Python 3.8.3 to Python 3.11.4.  A strange 
problem appeared which was not there before:
I am using the win32clipboard backage (part of pywin32), and when I use 
SetClipboardData() to write text which consists ENTIRELY OF DIGITS to 
the clipboard, I either get an error (not always the same error message) 
or a program crash.  The problem does not appear if I use 
SetClipboardText() instead.

Sample program:

from win32clipboard import *
OpenClipboard()
SetClipboardData(CF_UNICODETEXT, "A")
SetClipboardData(CF_UNICODETEXT, "A0")
SetClipboardData(CF_UNICODETEXT, "0A")
SetClipboardText("0", CF_UNICODETEXT)
print("OK so far")
SetClipboardData(CF_UNICODETEXT, "0")
CloseClipboard()

Sample output:

OK so far
Traceback (most recent call last):
  File "R:\W.PY", line 8, in 
    SetClipboardData(CF_UNICODETEXT, "0")
pywintypes.error: (0, 'SetClipboardData', 'No error message is available')

I can get round the problem by using SetClipboardText().  But can anyone 
shed light on this?
