Discussion on: How to convert .py to .exe? Step by step guide.

I'm a VERY inexperienced python user, but have built a couple of very basic scripts with an small interactive UI (using Tkinter/pyodbc).

My question is - once the script is converted to .exe and distributed to the users (who will save and launch from the desktops), do they need to have anything else installed, or is the .exe truly fully self contained?

My goal is to be able to write a script, convert to an executable, send to my users, and have them use that for some basic daily work.

Hi! To use .exe an end user doesn't need anything. Once it's .exe and not .py format your script should be usable without any additional software. Check for correct paths if you're opening smt inside your program.

But make sure (if you work with SQL DB) that it's packed with evething it needs. I haven't tried to work with DB and PyInstaller so I dont know how it will be able to pack it. I guess to PyInstaller it's just the same library as any other.

Thank you for the reply!

It seems that that's not always the case, and the converted .exe doesn't always contain the same stuff.

For example, and I apologize for not having the code and error messages anymore... I had a script (in PyCharm) that pulled a 2 values from a SQL table, then just subtracted them and printed out the difference (up to the thenth position). It worked fine, but once I converted it, I received an error that the "Decimal" module/library could not be found. I never called "Decimal", but one of my colleagues said it was part of the standard python installation. So we assumed the issue, then, was that the "Decimal" library/module/package was excluded from the final build.

I've since been unable to resolve this problem and built the app using something else, but I'd love to try again sometime.
