• pickleDB · Lightning-Fast Key-Value Store for Python

Das Beispiel von der pickledb-Webseite:

from pickledb import PickleDB
 
# Bind to a JSON file; no I/O yet
db = PickleDB("data.json")
db.load()
 
db.set("username", "alice")
db.set("theme", {
    "color": "blue",
    "font": "sans-serif"
})
 
print(db.get("username"))  # → "alice"
 
db.save()  # atomically write to disk

• SQLite

import os
import sqlite3
 
 
DB = "~/python.sqlite3"
 
 
DB = os.path.expanduser(
    os.path.expandvars(DB)
)
if not os.path.exists(DB):
    pass
 
con = sqlite3.connect(DB)
cur = con.cursor()
cur.execute("CREATE TABLE IF NOT EXISTS ...")
