Python class public method and private method

Sometimes we need to make some private and public function for a class.
Lets see python syntex for such class

 
#publicVsPrivate.py

class MyClass():

    def myPublicFunction(self):
        print "I am public function"

    def __myPrivateFunction(self):
        print "I am private function"


myClass= MyClass()
myClass.myPublicFunction()
#myClass.__myPrivateFunction # This is will not work, __myPrivateFunction private method

Output:

I am public function
