Python isn't always easy

"It's harder than it might seem to create a stand-alone Python app. It's also harder than you might think to reliably back up SQLite databases, but Python has the tools for it. And while it's not easy to install Python on an air-gapped machine, it absolutely can be done."

"SQLite databases are single files, so backing them up just means copying them, right? Wrong. Make backups the proper way by using SQLite's own backup mechanisms."

Creating stand-alone Python apps is difficult because Python’s dynamism complicates packaging into a self-contained form. Backing up SQLite databases is also more complex than simply copying the database file, because proper backups require using SQLite’s built-in backup mechanisms. SQLite databases are single files, but copying them can be unreliable. Python includes tools that support correct backup practices for SQLite. Installing Python on an air-gapped machine is not easy, but it can be done, enabling Python-based workflows in isolated environments.
