Question

我希望这段代码只捕获一个EOFError，但是，它捕获所有异常...

struct ContentView: View {
   @GestureState var magnifyBy = CGFloat(1.0)
   @State var zoomIn = CGFloat(1.0)

    var magnification: some Gesture {
           MagnificationGesture()
               .updating($magnifyBy) { currentState, gestureState, transaction in
                gestureState = currentState
           }.onEnded{value in
               magnifyBy = value
        }
    }

    var body: some View {
           Circle()
               .frame(width: 100 * magnifyBy,
                      height: 100 * magnifyBy,
                      alignment: .center)
       }
}

但是没有，因为我遇到了NameError，它被捕获了：

    try:
        rpg.data.load("playerdata.dat")
    except EOFError:
        playerdata = rpg.data()
        titleList = ["Start", t.gray30("[DISABLED] Continue"), "Help/Credits", "Exit\n\n" + "  *" + " "* int(stream.width()/tfactor) + t.white("CONTROLS:") + t.gray30("\n\t[ENTER] and [Z] - Confirm Selection\n\tArrow Keys - Move Cursor")]
    else:
        playerdata = rpg.data.load("playerdata.dat")
        titleList = ["Start", "Continue", "Help/Credits", "Exit\n\n" + "  *" + " "* int(stream.width()/tfactor) + t.white("CONTROLS:") + t.gray30("\n\t[ENTER] and [Z] - Confirm Selection\n\tArrow Keys - Move Cursor")]
    finally:
        title_screen = menuClosure(game_title, titleList, delay_ms = 24, tfactor = 6)

即使我没有其他try / except块

您的代码未捕获到NameError。最后，它们被扔到了您的“尝试除外”内部。似乎您尚未定义tfactor和titleList。

Python-除外所有错误的语句
