请注意10,11,24行的代码，是本条博客的精华，逻辑并不难，就是有些小语法问题比较纠结，记录一下。
import json
import sqlite3
import re

补充：python + sqlite3 基本操作
连接数据库
import sqlite3
# 连接数据库(如果不存在则创建)
conn = sqlite3.connect('test.db')
print("Opened database successfully")
# 创建游标
cursor = conn.cursor()
...
# 关闭游标
cursor.close()
# 提交事物
conn.commit()
# 关闭连接
conn.close()
创建表
... # 创建游标 cursor = conn.cursor() # 创建表 sql = 'CREATE TABLE Student(id integer PRIMARY KEY autoincrement, Name varchar(30), Age integer)' cursor.execute(sql) # 提交事物 conn.commit() ...
插入数据
...
# 创建游标
cursor = conn.cursor()
# 插入数据
sql = "INSERT INTO Student(Name, Age) VALUES(\'love\', 22)"
cursor.execute(sql)
# 插入数据 2
data = ('love2', 2221) # or ['love2', 2221]
sql = "INSERT INTO Student(Name, Age) VALUES(?, ?)"
cursor.execute(sql, data)
# 提交事物
conn.commit()
...
查询数据
...
# 创建游标
cursor = conn.cursor()
# 查询数据
sql = "select * from Student"
values = cursor.execute(sql)
for i in values:
print(i)
# 查询数据 2
sql = "select * from Student where id=?"
values = cursor.execute(sql, (1,))
for i in values:
print('id:', i[0])
print('name:', i[1])
print('age:', i[2])
# 提交事物
conn.commit()
...
其他操作
自增字段起始位置
# 设置起始值为1 update sqlite_sequence SET seq = 0 where name = '表名'; # 设置全部表起始值为默认值 delete from sqlite_sequence where name='TableName'; --注意表名区分大小写
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
