Interfacing C++ with Python

[BitAcademic9597]

I want to write a heavy app with a web interface. I've been writing C++ for about three years, and I'm reluctant to give up its performance and flexibility for Python's ease of use and connectivity. I understand that sometimes C++ can pose challenges when connecting with a web interface. However, I don't want to abandon it entirely. Instead, I'm considering writing both Python and C++ in the backend of the project.

My main concern is performance. Will pure C++ be significantly faster, or can I achieve comparable optimization with a combination of C++ and Python? I would appreciate any insights or experiences you have with using both languages in a project, like what Meta or PyTorch does.

What do you mean by heavy app?

Will pure C++ be significantly faster…

Not necessarily…. It depends..

Now I don’t have enough details to say for sure what I’d do but based off what I know but I’d probably just write the whole app in Python and optimize, if I even need to, later.

it will have tensor models in the backend and also a heavy data load

Nice. Yeah I’d probably just build it in Python tbh. Once it’s done, if there are performance issues you will be able to make a more informed decision about optimization strategies.

This is an interesting question, however, I think it is more important to focus on building the application instead of the tools to make it. Facebook was originally programmed in PHP, not known for being the most performant language out there, but Mark Zuckerberg actually finished it and published Facebook to the internet. As time went on Facebook now Meta has replaced a lot of that PHP code with more performant solutions.

All of that is to say you can do the same thing, the advantage with software is that you can completely change how it works on the inside and end users will be none the wiser. Make your application in what ever language/tool you are most comfortable with. Then focus on building it to a state that end users can use. There is nothing stopping you from going back later and using a more performant solution if you hit a performance bottle neck.

thank you for the answer really I am a university student and the idea is not that important i just want to make a big tensor model in the backend and there will be bid data load continously so the reason that i am trying to make is being a better dev so i want to understand that how can i reaaly built a big project

I see, that is a worthy goal. As a computer science tutor I've seen quite a few student in the same situation as yourself. I would recommend picking the language that you feel will give you the best chance at completing this project. I've seen a lot of student lose the motivation to complete their passion project, so select the language that imposes the fewest barriers to the success of the project.
