How to pass a method as argument in an another method?

Hey thanks for the response. I guess we don't need an init function here. Checkout the trimmed the code.

#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)
