Print("Connection is established: Database is created in memory")įirst, we import the sqlite3 module, then we define a function sql_connection. This database is called in-memory database.Ĭonsider the code below in which we have created a database with a try, except and finally blocks to handle any exceptions: import sqlite3 This database file is created on disk we can also create a database in RAM by using :memory: with the connect function.
