This is the reason for hiding calls to Process() inside if __name__ == "__main__" since statements inside this if-statement will not get called upon import. 由于Windows没有fork,多处理模块启动一个新的Python进程并导入调用模块。 如果在导入时调用Process(),那么这将启动无限继承的新进程(或...
PyAutoGUI 提供了pyautogui.dragTo()和pyautogui.drag()函数来将鼠标光标拖动到一个新位置或相对于当前位置的位置。dragTo()和drag()的参数与moveTo()和move()相同:x 坐标/水平移动,y 坐标/垂直移动,以及可选的持续时间。(鼠标移动过快时 MacOS 无法正确拖动,建议传递一个duration关键字参数。) 要尝试这些...
4.4. break 和continue 语句,以及循环中的 else 子句 break 语句,和 C 中的类似,用于跳出最近的 for 或while 循环. 循环语句可能带有 else 子句;它会在循环耗尽了可迭代对象 (使用 for) 或循环条件变为假值 (使用 while) 时被执行,但不会在循环被 break 语句终止时被执行。 以下搜索素数的循环就是这样的...
