如何在python中创建数据库文件

如何用python创建数据库文件

import sqlite3
from sqlite3 import Error

def create_connection(db_file):
    """ create a database connection to a SQLite database """
    conn = None
    try:
        conn = sqlite3.connect(db_file)
        print(sqlite3.version)
    except Error as e:
        print(e)
    finally:
        if conn:
            conn.close()

if __name__ == '__main__':
    create_connection(r"C:\sqlite\db\pythonsqlite.db")

您当前的代码是否有效？如果不是，您会得到什么错误？你预计会发生什么？

import sqlite3
from sqlite3 import Error

def create_connection(db_file):
    """ create a database connection to a SQLite database """
    conn = None
    try:
        conn = sqlite3.connect(db_file)
        print(sqlite3.version)
    except Error as e:
        print(e)
    finally:
        if conn:
            conn.close()

if __name__ == '__main__':
    create_connection(r"C:\sqlite\db\pythonsqlite.db")
