Operational error at cursor when creating function in SQLite - database

Question

I am trying to insert data into my SQLite database, it goes fine until I get the error while creating a function for DB. It sends OperationalError at cursor.
I couldn't find solution for my problem.
Code I'm using:
import sqlite3
from sqlite3 import *
SQL_CREATE_STATEMENT = '''CREATE TABLE password
(id integer PRIMARY KEY NOT NULL,username text, password text, source text)'''
SQL_INSERT_STATEMENT = '''INSERT INTO password (username, password, source)VALUES({},{},{});'''
DATABASE_PATH = 'home/taha/lessons/projects/passStorage/passDB.db'
DATA = dict()
def create_connection(db_file):
try:
conn = sqlite3.connect(db_file)
return conn
except Error as e:
return e
def create_table(connection, sql_commands):
c = connection.cursor()
c.execute(sql_commands)
print('done')
def get_input():
USERNAME = input('username: ')
PASSWORD = input('password: ')
SOURCE = input('source: ')
return USERNAME,PASSWORD,SOURCE
def insert_date(connection, data):
c = connection.cursor()
c.execute(SQL_INSERT_STATEMENT.format(data.values))
def main():
conn = create_connection(DATABASE_PATH)
create_table(conn, SQL_CREATE_STATEMENT)
user_info = get_input()
DATA['username'], DATA['password'], DATA['SOURCE'] = user_info
insert_date(conn, DATA)
if __name__ == '__main__':
main()
I expect no error but it sends this:
c = connection.cursor()
AttributeError: 'OperationalError' object has no attribute 'cursor'

Answer 1

def create_connection(db_file):
try:
conn = sqlite3.connect(db_file)
return conn
except Error as e:
return e # <-- here you return OperationalError instance
AttributeError: 'OperationalError' object has no attribute 'cursor'
Shows that OperationalError has no attribute cursor
Add additional logic that check connection here.
I believe the core of your problem is wrong file path:
DATABASE_PATH = 'home/taha/lessons/projects/passStorage/passDB.db'
But I believe should be
DATABASE_PATH = '/home/taha/lessons/projects/passStorage/passDB.db'
