Many times though, a program results in an error after it is run even if it doesn't have any syntax error. Such an error is a runtime error, called an exception. A number of built-in exceptions are defined in th
其中一个常见的错误就是“python pywintypes.error: (2, ‘OpenEvent’, ‘系统找不到指定的文件。’)”。这个错误一般发生在使用pywin32库进行Windows系统编程时,主要是因为找不到指定的文件而导致的。 在本文中,我将向你展示解决这个错误的步骤和具体的代码实现。 2. 解决步骤 以下是解决“python pywintypes.e...
