I solved it with simple if condition and without using init
#calculator class with arithmetic methods
class calc:
def execute(self, func, a, b):
self.a = a
self.b = b
if func == "add":
self.add()
elif func == "sub":
self.sub()
elif func == "mul":
self.mul()
elif func == "div":
self.div()
def add(self):
print (self.a,"+",self.b,"=",self.a + self.b)
def sub(self):
print (self.a,"-",self.b,"=",self.a - self.b)
def mul(self):
print (self.a,"*",self.b,"=",self.a* self.b)
def div(self):
print (self.a,"/",self.b,"=",self.a / self.b)
cal = calc()
cal.execute("div", 6, 3)
