You know about encapsulation. You know about private methods that are only accessible from inside a class -- not outside. You want to encapsulate a method in a class in Python. How do you write such a program?
Here is an example. If you uncomment the "goodwidget.__makeone()", you will see the program fail; you will see the private method __makeone() work in this program if you run it exactly how it appears below (using Python 3):
#!/usr/bin/env python class widgetfactory: def __init__(self): self.__makeone() def funtest(self): # This is a public method. print('This widget is working!') def __makeone(self): # This __ syntax tells Python it is a private method. print('creating one widget; please wait...') goodwidget = widgetfactory() goodwidget.funtest() #goodwidget.__makeone() # If you uncomment this line, this line will cause the program to throw an error.
