python实现得到一个给定类的虚函数

python virtual function

本文实例讲述了python实现得到一个给定类的虚函数的方法,分享给大家供大家参考。具体如下:

现来看看如下代码:

import wx 

for method in dir(wx.PyPanel):   #这里改成给定的类 
  if method.startswith("base_"): 
    print method 

Copy after login

输出的结果为:

base_AcceptsFocus
base_AcceptsFocusFromKeyboard
base_AddChild
base_DoGetBestSize
base_DoGetClientSize
base_DoGetPosition
base_DoGetSize
base_DoGetVirtualSize
base_DoMoveWindow
base_DoSetClientSize
base_DoSetSize
base_DoSetVirtualSize
base_Enable
base_GetDefaultAttributes
base_GetMaxSize
base_InitDialog
base_OnInternalIdle
base_RemoveChild
base_ShouldInheritColours
base_TransferDataFromWindow
base_TransferDataToWindow
base_Validate 

Copy after login

另附一个常用的str的方法,官方文档如下:
str.startswith(prefix[,start[,end]])

Return True if string starts with theprefix, otherwise returnFalse.prefix can also be a tuple of prefixes to look for. With optionalstart, test string beginning at that position. With optionalend, stop comparing string at that position.

如果string以prefix开头,函数返回True.

希望本文所述对大家的Python程序设计有所帮助。

What is the function of C language sum? What is the function of C language sum? Apr 03, 2025 pm 02:21 PM

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

Is distinctIdistinguish related? Is distinctIdistinguish related? Apr 03, 2025 pm 10:30 PM

Although distinct and distinct are related to distinction, they are used differently: distinct (adjective) describes the uniqueness of things themselves and is used to emphasize differences between things; distinct (verb) represents the distinction behavior or ability, and is used to describe the discrimination process. In programming, distinct is often used to represent the uniqueness of elements in a collection, such as deduplication operations; distinct is reflected in the design of algorithms or functions, such as distinguishing odd and even numbers. When optimizing, the distinct operation should select the appropriate algorithm and data structure, while the distinct operation should optimize the distinction between logical efficiency and pay attention to writing clear and readable code.

How to understand !x in C? How to understand !x in C? Apr 03, 2025 pm 02:33 PM

!x Understanding !x is a logical non-operator in C language. It booleans the value of x, that is, true changes to false, false changes to true. But be aware that truth and falsehood in C are represented by numerical values ​​rather than boolean types, non-zero is regarded as true, and only 0 is regarded as false. Therefore, !x deals with negative numbers the same as positive numbers and is considered true.
