I just compiled a non-ui PyBridge program and the build folder was 68MB. ( I do have python separate on my machine)

And a UI version came out at 96MB

So, the app installer must download and install Python...

No.

I've published an example: https://www.b4x.com/b4j/files/PyPDF_Example.exe
It is 49mb. Not much larger than a package without Python. And this example includes several Python libraries. It can be smaller.

Obviously if you use large Python libraries then the package will be larger. And not every library is really suitable for simple distribution.

Click to expand...

But some runtime of the Py is needed or not for standalone app ?

Ahh, i see now that 65 MB of "WinPython" is included, clear now, thanks, Erel.
Totally 120 MB of the installed app.

Step 1: Work with a local Python:



No more special steps.




The local Python runtime is copied to the installer package.

BTW, after uninstallation - the app folder is not deleted, with big tree of the empty subfolders:
