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 

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 

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。
