f2的parent frame是哪个? global frame下result变量绑定的值是什么? 答案 想要回答这些问题,我们需要理清楚这些函数和frame之间的关系。 首先第一个问题,add_ten指向的函数对象是make_adder函数的执行结果,这个执行结果我们读代码可以知道,是一个lambda函数。所以add_ten指向的函数名称应该是lambda。其次这个lambda的paren...

创建一个自定义的窗口类,继承自 Tkinter 的 Frame 类。 重写自定义窗口类的构造方法,设置窗口的属性。 添加方法以控制窗口的显示和隐藏。 创建实例并测试隐藏窗口的效果。 下面我们将逐步展开每个步骤,并给出相应的代码示例。 步骤1:创建自定义窗口类
以下是`frame`函数的基本用法: ```python import inspect def my_function(): frame = inspect.currentframe() #获取当前堆栈帧对象 #进一步操作堆栈帧对象... frame_info = inspect.getframeinfo(frame) print("当前函数所在文件名:", frame_info.filename) print("当前函数所在行号:", frame_info.lineno) ...
watchpoints will try to guess what you want to monitor, and monitor it as you expect(well most of the time) unwatch When you are done with the variable, you can unwatch it. fromwatchpointsimportwatch, unwatch a =0watch(a) a =1unwatch(a) a =2# nothing will happen ...
The [C++ view] node provides a representation of the underlying C/C++ structure for a value, identical to what you see in a native frame. It shows an instance of _longobject (for which PyLongObject is a typedef) for a Python long integer, and it tries to infer types for native c...
Instead, this section provides a very quick orientation to what a Tkinter application looks like, identifies foundational Tk concepts, and explains how the Tkinter wrapper is structured. The remainder of this section will help you to identify the classes, methods, and options you'll need in your...
