I made a cool little project for my friend, basically a timer using tkinter, but I am confused on how to let them access this project without having vscode or pycharm. Is it possible for them to just see the Tkinter window or something like that?  Is there an application for this? Sorry if this is a stupid question.
You can just built an .exe (Application) of your project. Then just share the application file and anyone can use the application through .exe. You can use pyinstaller to convert your python code to exe.
pip install pyinstaller
then cd to the project folder then run the following command
pyinstaller --onefile YourFileName.py
if you want to make exe without console showing up then use this command
pyinstaller --onefile YourFileName.py --noconsole
How do you set up a python project to be able to send to others without them having to manually copy and paste the code into an editor
