python3 連線sqlite例項，直接上程式碼吧
import sqlite3
db = r"D:\pyWork\test.db" #pyWork目錄下test.db資料庫檔案
drp_tb_sql = "drop table if exists staff"
crt_tb_sql = """
create table if not exists staff(
id integer primary key autoincrement unique not null,
name varchar(100),
city varchar(100)
);
"""
#連線資料庫
con = sqlite3.connect(db)
cur = con.cursor()
#建立表staff
cur.execute(drp_tb_sql)
cur.execute(crt_tb_sql)
#插入記錄
insert_sql = "insert into staff (name,city) values (?,?)" #?為佔位符
cur.execute(insert_sql,('Tom','New York'))
cur.execute(insert_sql,('Frank','Los Angeles'))
cur.execute(insert_sql,('Kate','Chicago'))
cur.execute(insert_sql,('Thomas','Houston'))
cur.execute(insert_sql,('Sam','Philadelphia'))
con.commit()
#查詢記錄
select_sql = "select * from staff"
cur.execute(select_sql)
#返回一個list，list中的物件型別為tuple（元組）
date_set = cur.fetchall()
for row in date_set:
print(row)
cur.close()
con.close()
