在Python程序中获取“NotImplementedError”[已关闭]

Question

错误：

C:\Users\wande\PycharmProjects\pythonProject\venv\Scripts\python.exe C:\Users\wande\PycharmProjects\pythonProject\main.py 
Unhandled exception in listener callback
Traceback (most recent call last):
  File "C:\Users\wande\PycharmProjects\pythonProject\venv\lib\site-packages\pynput\_util\win32.py", line 386, in _handler
    converted = self._convert(code, msg, lpdata)
  File "C:\Users\wande\PycharmProjects\pythonProject\venv\lib\site-packages\pynput\_util\win32.py", line 401, in _convert
    raise NotImplementedError()
NotImplementedError

During handling of the above exception, another exception occurred:

    minhaPrint.save(os.path.join(diretorioRaiz, + "printkeylogger_" + horarioPrint + ".jpg"))
TypeError: bad operand type for unary +: 'str'

代码：

def on_click(x, y, buttom, pressed): if pressed: minhaPrint = py.screenshot() hora = datetime.now() horarioPrint = hora.strftime,("%H:%M:%S,") minhaPrint.save(os.path.join(diretorioRaiz, + "printkeylogger_" + horarioPrint + ".jpg")) 

Answer 1

您收到的错误是 TypeError。这意味着 Python 正在尝试对不支持的数据类型执行操作。在这种情况下，发生错误是因为您尝试使用一元运算符连接字符串。

导致错误的代码行是：

minhaPrint.save(os.path.join(diretorioRaiz, + "printkeylogger" + horarioPrint + ".jpg"))

该行中的

+

符号是一元运算符。它用于否定一个值。然而，字符串不能被否定。因此，Python 会给你一个错误。

要修复此错误，您需要从代码行中删除

+

符号。这将允许 Python 正确地将字符串与文件路径连接起来。

更正后的代码行是：

minhaPrint.save(os.path.join(diretorioRaiz, "printkeylogger" + horarioPrint + ".jpg"))

完成此更改后，代码应该可以正常运行，不会出现任何错误。
