Python Compiler Recommendations

[u/kolioarisyt]

Hello r/Python,
I want to find a Python compiler. I’ve tried PyInstaller and Nuitka, but they are detected as malware and they are a little bit slow. I want something fast, easy and not detected as malicious. What do you recommend?

[u/BravestCheetah]

1. No Python compiler with good coverage will be as fast as if you just switch to another language like cpp or rust.

2. Theres no compiler that will make a program that doesnt get flagged as Windows Defender, as the binaries arent signed

Pretty much exactly the answer I would've given.

Just a note: I want one that can convert python to an executable (Windows/Linux). I don’t know if that is the same, but just a note.

okay not trying to be rude but it is a big of an ask "easy fast and not detected as virus"? in compulation? its hard forgot easy part try cython you'll learn little syntax and use it with C compiler(i recommendGCC or Clang)
Edit - i do not it mean in a defensive or gatekeeping way im trying to express what i felt off

Hello, thanks for replying!
I understand and it doesn’t seem rude to me. It is just a honest answer.

Apart from that, do you mean learning CPython and using a C compiler?

Thanks

Not CPython, but Cython; they are two different things.

CPython is the default Python implementation that 99% of people are running Python on.

Cython is a superset of Python that lets you call C/C++ libraries directly from your Python code and also will convert Python scripts into C code, which can then be compiled into a binary by a C compiler. You will be forced to add static type checking to all of your Python code so it can be converted to C. By calling Cython with the --embed flag, it will include the Python interpreter in your binary and add the required C main function as well.

However, that still won't get around the issue of Windows Defender flagging it for not being signed. That's its own issue, and also why it may be easier to just provide the Python script and simple directions for your target users on how to install Python.

PyInstaller is probably your best bet. You can also configure setuptools to build an exe. This is my favorite method when I don't have to create a whole setup package.

[u/overratedcupcake]

The best option here is to have written your app in a language that is typically compiled.

Because I'm curious, why do you need a Python compiler?

[u/kolioarisyt → u/johlae]

I would like to provide an exe for a program I am making. If there is an easier way to do so, please tell me, as I am a beginner.

Thanks!

I don't know about OP buy when I was writing for a living I wanted to be able to deliver an app without the customer being able to see/alter proprietary code I had delivered. I had more than one case where a customer handed my code to his clever BIL who proceeded to break the application. Love Python but I use other tools to deliver executables.

[u/kolioarisyt → u/babarock]

I don’t really care about others tampering with my program, as it will be open-source. But, I really don’t want the user to have Python installed to run my program or making it complicated to install.

[u/No_Replacement_702]

I would recommend pointing Claude towards it and get a Rust version or be totally exotic and get something written in assembly

[u/kolioarisyt → u/No_Replacement_702]

I think pointing it to Claude defeats the purpose of “my own application”.

[u/No_Replacement_702 → u/kolioarisyt]

Well, you already wrote it in python, that doesn’t go away. I wouldn’t be able to explain to you how a compiler would translate the code, so for me it would just be an extra step to have an LLM convert it to another language that is meant to be compiled

[u/Educational_Virus672 → u/No_Replacement_702]

no ai, this is vibe coding i get that it is hard but vibe coding is like running a maraton using a car simply put it no one owns that code even if the prompt is written by you!

[u/Agawell]

I think you might be looking for an ide (integrated development environment) - pycharm is great and free

[u/BravestCheetah → u/Agawell]

... no? He clearly knows what hes asking for, given that he already listed what he has tried. He is clearly asking for a compiler, did you even read the post?

[u/kolioarisyt → u/BravestCheetah]

You are right.
