python 读取.db文件并保存为xlsx文件

import sqlite3
import pandas as pd




def ReadDB(path:str):
    # create a sql connection to our sqlite database
    try:
        conn = sqlite3.connect(path)
    except Error as e:
        print(e)
    # creating cursor
    cursor = conn.cursor()
    # reading all table names
    table_list = [a for a in cursor.execute("SELECT name FROM sqlite_master WHERE type = 'table'")]
    # here is your table list
    print('table_list is :\n', table_list)
    for tab in table_list:
        df = pd.read_sql_query('SELECT * FROM {}'.format(tab[0]), conn)
        conn.commit()
        print('table ', tab[0], 'head is :\n', df.head())
        print('table ', tab[0], 'shape is :\n', df.shape)
        df.to_excel('./'+tab[0]+'.xlsx')
    cursor.close()
    conn.close()
    return


# createing file path
path = './test.db'
ReadDB(path)

结果如下：
