You can generate a binary of your script (and all dependencies) with pyinstaller[1], and then your users don't have to worry about anything other than running the binary.

> PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules. PyInstaller supports Python 3.7 and newer, and correctly bundles many major Python packages such as numpy, matplotlib, PyQt, wxPython, and others.
