How we can print the value of c in given problems

here is the problems which is related to python oops class Calculator: def __init__(self,a,b): self.a=a self.b=b def add(self,c): return self.a + self.b + c def mul(self): return self.a * self.b def sub(self): return self.a - self.b val1=Calculator(23,1) p=val1.add(4) print(val1.a) print(val1.b)

Is there any method to print c without making self.c variables or not ????

one way is to make a self.c variable, then assign it to the value that is placed in the add method inside the method itself before returning. that way, you can print out self.c and get the value after the fact.

Yeah, you can print everything inside the function. or you can make the variable a global variable Not reccomended. Why? Its 10x easier to just add a 3rd number right at the beggining and then you dont worry about any of this

it wouldn't be the value of c. variable c is just a parameter that is added to the solution of self.a and self.b when the add() method is called to print that value: print(val1.add(5)) #print(21 + 1 + 5) # output 29
