$ python function_global.py x is 50 Changed global x to 2 Value of x is 2 1. 2. 3. 4.global 语句用以声明 x 是一个全局变量——因此,当我们在函数中为 x 进行赋值时,这一改动将影响到我们在主代码块中使用的 x 的值。 你可以在同一句 global 语句中指定不止一个的全局变量,例如 global x...
Because the Python error state is still set when SWIG::DirectorMethodException is thrown, Python will register the exception as soon as the C wrapper function returns. 本示例中使用的 SWIG::DirectorException 类实际上是 SWIG::DirectorMethodException 的基类,因此它将捕获此异常。由于抛出 SWIG::...
