So, I was just looking for a tutorial for sqlite3 python. Some people use the database name with db.myDb, and others use myDb.db. Can anyone explain the difference between the format names?
It does not matter which file-extension a database has to its functionality. It is just a name, so reading and writing will work the same.
Most Operating-Systems use the extension to determin wich icon to show in a file-browser or with which application to open a specific file. So choosing the right file-extensions for your database improves your workflow.
Typical extensions for sqlite3 are:
.sqlite.sqlite3.db.db3.sdb.s3db
