Is it possible to have overloaded functions in Python? In C# I would do something like void myfunction (int first, string second) { # Some code } void myfunction (int first, string second, float

Jan 1, 2016 · It is impossible by definition to overload a function in python (read on for details), but you can achieve something similar with a simple decorator class overload:

Apr 18, 2012 · Python 3.x includes standard typing library which allows for method overloading with the use of @overload decorator. Unfortunately, this is to make the code more readable, as the @overload decorated methods will need to be followed by a non-decorated method that handles different arguments.

I want to be able to initialize the class with, for example, a filename (which contains data to initialize the list) or with an actual list. What's your technique for doing this? Do you just check the type by looking at __class__? Is there some trick I might be missing? I'm used to C++ where overloading by argument type is easy.

Feb 2, 2023 · Python does not support overloading. The best that you can do is remove any type identifiers from the arguments and use if-else statements to change the function of the method depending on the input types.

Aug 17, 2014 · Of course, python can't do this, because it has dynamic typing. When I searched for how to mimick method overloading, all answers just said "You don't want to do that in python".

The fact is that function overloading is based on the idea that passing different types you will execute different code. If you have a dynamically typed language like Python, you should not distinguish by type, but you should deal with interfaces …

Dec 28, 2011 · When a compiler or interpreter looks up the function definition, then, it uses both the declared name and the types of the parameters to resolve which function to access. So the logical way to implement overloading in Python is to implement a wrapper that uses both the declared name and the parameter types to resolve the function.

Mar 16, 2012 · Python doesn't do function overloading. This is a consequence of it being a loosely-typed language. Instead you can specify an unknown number of arguments and deal with their interpretation in the function logic. There are a couple ways you can do this. You can specify specific optional arguments: def func1(arg1, arg2=None): if arg2 != None:

Dec 1, 2022 · Is it possible to do function overloading in Python like in Java (i.e. with out the branching)? Is there is a clear way using a decorator or some library?
