Since Python is a object oriented programming language then you can use things like classes to define a object, a class is a bunch of methods that act on the data that is stored within the class itself. You can store data within the class, but unlike c++\/java\/c# etc, there is no private\/public\/protected, everything is public accessible.<\/p>\n
In the example below, the class constructor is called (__init__ method) and the first parameter is the class object itself, which is why it is there and for many reasons why it is called self as a variable name.<\/p>\n
\r\n\r\n# self means the object itself.\r\n\r\nclass mysimpleclass :\r\n __myvar = 0\r\n def __init__(self,value = 0) :\r\n self.__myvar = value\r\n\r\n def printValue(self) :\r\n print self.__myvar\r\n\r\nsimple = mysimpleclass(5)\r\nsimple.printValue()\r\n<\/pre>\nthe printValue method just does that, it will print the value that is sorted within the class object and here is the output<\/p>\n
\r\n5\r\n<\/pre>\n if you did not put in the self in the example above for printing out the class object variable __myvar as below<\/p>\n
\r\nclass mysimpleclass ....\r\n ....\r\n def printValue() :\r\n print __myvar\r\n<\/pre>\nthe error would be<\/p>\n
\r\nNameError: global name '_mysimpleclass__myvar' is not defined\r\n<\/pre>\nbecause the interrupter is looking for a global variable and not a variable attached to that object.<\/p>\n","protected":false},"excerpt":{"rendered":"
