Making it Pythonic: create a sqlite3 database if it doesn't exist?

Question

I wrote a Python script which initializes an empty database if it doesn\'t exist.

import os

if not os.path.exists(\'Database\'):
    os.makedirs(\'Database\')
          


        

Answer 1

Create directory path, database file and table

Here is a recipe to create the directory path, database file and table when necessary. If these already exist, the script will overwrite nothing and simply use what is at hand.

import os
import sqlite3

data_path = './really/deep/data/path/'
filename = 'whatever'

os.makedirs(data_path, exist_ok=True)

db = sqlite3.connect(data_path + filename + '.sqlite3')
db.execute('CREATE TABLE IF NOT EXISTS TableName (id INTEGER PRIMARY KEY, quantity INTEGER)')
db.close()
