Methods with the same name in one class in Python

Question

How can I declare a few methods with the same name, but with different numbers of parameters or different types in one class?

What must I change in the following class?

Answer 1

You can have a function that takes in a variable number of arguments.

def my_method(*args, **kwds):
    # Do something

# When you call the method
my_method(a1, a2, k1=a3, k2=a4)

# You get:
args = (a1, a2)
kwds = {'k1':a3, 'k2':a4}

So you can modify your function as follows:

def my_method(*args):
    if len(args) == 1 and isinstance(args[0], str):
        # Case 1
    elif len(args) == 2 and isinstance(args[1], int):
        # Case 2
    elif len(args) == 2 and isinstance(args[1], str):
        # Case 3
