Calling a function from another function within the same class

[cindrajit]

class calculator():
    def __init__(self,x=0,y=0):
        self.first=x
        self.second=y
        #calculator.param=+theta
   
    def scaleparam(self,theta):
        self.theta=theta
        return self.theta

    def addition(self,theta):
        self.addition1=(self.first+self.second)*self.scaleparam(theta)
        return self.addition1
   
        

check1=calculator(3,4)  

check1.scaleparam(10)

print "the addition1 is "+str(check1.addition())

## Got error TypeError: addition() takes exactly 2 arguments (1 given)##

You need to define identifier theta and pass theta to the function call as in:

theta = 1
print "the addition1 is "+str(check1.addition(theta))
