the fundamental difference is: a python dict lives in RAM and is destroyed when your program is finished running. a SQL database exists on disk and persists after your program is finished running. You COULD save a python dict to disk using the pickle module, and you could absolutely implement a simple database this way. In that case, SQL is just a more robust and mainstream purpose-built version with more powerful features. Answer from spez_edits_thedonald on reddit.com

Getting the most out of SQLite3 with Python
Of course, if you know beforehand how many results you want, you can use the LIMIT SQL statement instead, but Python generators are very handy and allow you to decouple data generation from data consumption. Shit happens, even in the middle of a SQL transaction. To avoid having to deal manually with rollback or commit, you can simply use the connection object as a context manager. In the following example we create a table, and insert by mistake duplicated values: import sqlite3 connection = sqlite3.connect(':memory:') with connection: connection.execute( 'CREATE TABLE events(ts, msg, PRIMARY

r/learnpython on Reddit: What is the point of sqlite in python?
March 2, 2021 -
I'm working on a project that requires loading data from csv files into an sqlite database via python. Each csv becomes its own table in the database. The data is going to be used for an optimization model.
My question is - why can't these tables just be created as python dictionary objects? What is the point of creating sqlite databases and cursors, fetching, etc.? It seems to me that python dictionaries can be filtered just as easily, and you cut out the extra sqlite steps.

You don't need (to install) any additional Python modules to use sqlite3.
If the database doesn't exist, it will be automatically created usually in the same directory as the script.
On running your script, I get this :-
$ ls *.db
ls: *.db: No such file or directory
$ python test.py
$ ls *.db
mydatabase.db
$ sqlite3 mydatabase.db
SQLite version 3.7.7 2011-06-25 16:35:41

Sqlite3 is the version commonly used with Python. If you are running Windows, you need to download sqlite download from official page. If you are using Ubuntu or Debian based system then it comes pre-installed.
Now coming to python, sqlite3 is the package name, it comes included with python, if you don't find it, then install it with the command apt-get install python-sqlite on Ubuntu system.
Considering you are using Ubuntu system, simply type sqlite3 test.db to create database name test.db.
As for your program:
import sqlite3
conn = sqlite3.connect("test.db") # connect to test.db
cursor = conn.cursor() # get a cursor to the sqlite database
# cursor is the object here, you can use any name
# create a table
cursor.execute("""CREATE TABLE albums
(title text, artist text, release_date text,
publisher text, media_type text)""")
# cursor.execute is used to execute any command to sqlite
Few more function I would like to introduce is data = cursor.fetchone() to fetch one row, data = cursor.fetchall() to fetch many rows at once and store in tuple data.
