Question

I am new to Python. I was trying to define and run a simple function in a class.

Can anybody please tell me what’s wrong in my code:

class A :     def m1(name,age,address) :         print('Name -->',name)         print('Age -->',age)         print('Address -->',address)   >>> a = A() >>> a.m1('X',12,'XXXX') Traceback (most recent call last):   File '<pyshell#22>', line 1, in <module>     a.m1('X',12,'XXXX') 

I am getting below error
TypeError: m1() takes exactly 3 positional arguments (4 given)

Answer 1

Instance methods take instance as first argument:

class A :     def m1(self, name,age,address) :         print('Name -->',name)         print('Age -->',age)         print('Address -->',address) 

You can also use @staticmethod decorator to create static function:

class A :     @staticmethod     def m1(name,age,address) :         print('Name -->',name)         print('Age -->',age)         print('Address -->',address)
