Method Scope

Like global attributes, you may have methods that are accessible through the class itself rather than an instance of the class. These may also be known as static methods . They are not accessible by instances of the class. Depending on the class your building, it may help to have a method that is only accessible through the class and not the instances. Let’s see an example: 1| # understanding which methods are accessible via the class itself and class instances

3| class Dog( ):

4| sound = "bark"

6| def makeSound(self):

7| print(self.sound)

9| def printInfo( ):

10| print("I am a dog.")

12| Dog.printInfo( ) # able to run printInfo method because it does not include self parameter

14| # Dog.makeSound( ) would produce error, self is in reference to instances only

16| sam = Dog( )

18| sam.makeSound( ) # able to access, self can reference the instance of sam

20| # sam.printInfo( ) will produce error, instances require the self parameter to access methods
