Run generated .py files without python installation

Question

I am coding a PyQt5 based GUI application needs to be able to create and run arbitrary Python scripts at runtime. If I convert this application to a .exe, the main GUI Window will run properly. However, I do not know how I can run the short .py scripts that my application creates. Is it possible to runs these without a system wide Python installation?

I don't want ways to compile my python application to exe. This problem relates to generated .py scripts

@Andrew, please clarify your question. As you can see people think you are asking about turning a Python project to an `.exe` — Tomerikoo, Mar 14 '20 at 15:33
BTW, what does the main application create Python scripts for, instead of running the code they contain directly? — mkrieger1, Mar 14 '20 at 15:46

No, to run a Python file you need an interpreter.

It is possible that your main application can contain a Python interpreter so that you don't need to depend on a system-wide Python installation.

Yes, as I said it is possible. *How* to do this exactly, I can't explain here (I would have to research it myself, and it depends on your use case). – mkrieger1 Mar 14 '20 at 15:40

No, it won't work. But you can make a small tool that will load the scripts and eval them within the context of packed executable. Look here for more details. One thing to be mindful of is that your eval executable should import all the dependencies needed by your generated .py files

So that sounds better than the other answers here. I also heard that using ```eval``` is harmful or dangerous sometimes. Is it really that or I heard it wrong @Vlad – Abhay Salvi Mar 14 '20 at 15:43

@AndrewWhiteman I think that's pracically your question, not something to answer in a comment – Tomerikoo Mar 14 '20 at 15:53
