Python OOPS Syntax

OOPS Program

class Demo:
    def add(self):
        x=10
        y=20
        z=x+y
        print(z)
    def sub(self):
        x=10
        y=20
        z=x-y
        print(z)

    def mul(self):
        x=10
        y=20
        z=x*y
        print(z)
    def div(self):
        x=10
        y=20
        z=x/y
        print(z)

if __name__=="__main__":
    d=Demo()
    d.add()
    d.sub()
    d.mul()
    d.div()
