How to create a database file in python?

I’m not too sure how to link python to database using SQLite as the updateDB function isnt working. This code should work but the update isnt working correctly.

What am i missing?

import sqlite3

class Database: def init(self): self.DBName ='BUYHIRELtd.db'

def connect(self):
    conn = None
    try: 
        conn = sqlite3.connect(self.DBName)
    except Exception as e:
        print(e)
    return conn

def queryDB(self, command, params=[]):
    conn = self.connect()
    cur = conn.cursor()
    cur.execute(command, params)
    result = cur.fetchall()
    self.disconnect(conn)
    return result

def updateDB(self, command, params=[]):
    conn = self.connect()
    cur = conn.cursor()
    cur.execute(command, params)
    result = cur.fetchall()
    self.disconnect(conn)
    return result

def disconnect(self, conn):
    conn.close()

You are missing conn.commit to save changes to the database.

import sqlite3

class Connector:
    dbName = "Database.db"

    def connect(self):
        conn = None
        try:
            conn = sqlite3.connect(self.dbName)
        except Exception as e:
            print(e)
        return conn

    def disconnect(self, conn):
        conn.close()

    def queryDB(self, command, params=[]):
        conn = self.connect()
        cur = conn.cursor()

        cur.execute(command, params)
        result = cur.fetchall()

        self.disconnect(conn)
        return result

    def updateDB(self, command, params=[]):
        conn = self.connect()
        cur = conn.cursor()

        cur.execute(command, params)
        conn.commit()
        result = cur.fetchall()

        self.disconnect(conn)
        return result

make sure that you're importing sqlite3 in the top of the database.py file or the commands wont be able to run.
