Hello, as someone who runs most of their apps portable, I'm excited to find a portable version of python that I can carry with me. It's going to allow me to use my scripts everywhere I go, without having to compile them before-hand. I do have one question though...

From a normal cmd prompt, is it safe to pass my scripts to WPy64-3850\python-3.8.5.amd64\python.exe, or must I use WPy64-3850\WinPython Interpreter.exe in order to get all the portable features?

I don't want to leave anything behind on the host, however if you pass a .py file to WinPython Interpreter.exe, a terminal window will remain open after the script is run, which quickly adds up.

I know that with the PortableApps platform, not using the correct .exe will effectively void the portable traits of the app. The portable .exe adds various environment variables and configurations so that the underlying program becomes portable. I'm curious if it's the same case here.

Version: Winpython64-3.8.5.0dot.exe

I noticed that WinPython Interpreter.exe calls winpython.bat before launching python.exe.

I appended an extra line to the .bat with exit and it gives me the desired results, no terminal left open after exiting python. That said, the original question still stands.

hi @LeonT-A,

WinPython is:

Yet nowodays:

  • you can install the free VisualStudio yourself, if you need to compile cython programs,
  • you can play with environment variables in %HOME%\winpython.ini to make it more portable.
