Accessing Methods of a class using function parameter in python -

i have class in python:

class xyz:     def abc():           #do             def add(x,y):                   #add x , y             def sub(x,y):                   #subtract y x             def mul(x,y):                   #multiply x ynd y 

note: here "add", "sub" , "mul" nested methods.

1. is allowed make class this?

2. if allowed, want access methods "add", "sub" , "mul" function parameters. e.g.:

   from xyz import xyz def jkl(input):        abc.(input)  # doing raise syntax error. refernece. 

so, when call jkl(add(2,3)) should add numbers. when call jkl(sub(4,3)) should subtract numbers.

can done?

it's hard understand goal here.

edit: i'll leave answer here since has received upvote, op clarified they're asking how overload operators.

you can this:

class abc():       //do       @staticmethod       def add(x,y):               # add x , y       @staticmethod       def sub(x,y):               # subtract y x       @staticmethod       def mul(x,y):               # multiply x ynd y  abc.add(1,1) 

if want use class in module, can put class definition in file xyz.py, , in file (in same directory):

from xyz import abc  abc.add(1,1) 

however, odd thing in python world. i'd advise organizing things differently, unless have reason things way. better way skip class definition altogether, , in abc.py:

def add(x,y):           # add x , y def sub(x,y):           # subtract y x def mul(x,y):           # multiply x ynd y 

then import module:

import abc  abc.add(1,1) etc... 

alternatively, can this:

from abc import add, sub, mul  add(1,1) etc...
