python 查询sqlite数据库问题?

Question

学习中 --建表，添加数据 都过了，

用pycharm也可以查询，操作啊！！如图：

但是用python查询数据表示报错说没有这样的表报错如图:

代码如下:

import sqlite3

conn = sqlite3.connect(r'./mytest.py')
cursor = conn.cursor()

# sql = '''select * from students'''
sql = "select rowid, * from students"

results = cursor.execute(sql)
all_students = results.fetchall()
for student in all_students:
    print(student)
    

行了没问题了 劳烦大家了！！路径问题
conn = sqlite3.connect('D:\pycharm\lesson\sn01\SQL\mytest.db')

Answer 1

conn = sqlite3.connect(r'./mytest.py')
为啥连接的是py...
