Since we should only ever have one connection open (for writing to the database, at least), it can be simpler to create the connection object at the top of the file instead of inside the function.
#CONNECTING TO SQLITE DATABASE PYTHON CODE#
The best way to create a Sqlite database in Python: import the sqlite3 module use the nnect('databasename.db') funciton Follwoing is the Python code that create a. sqlite3 module is a python built-in module which have a lot of method for working with SQLite databases.
