我制作了一个包含以下内容的模块:

import sqlite3 as sq
connection = sq.connect("test.db")
cursor = connection.cursor()
cursor.execute("DROP TABLE IF EXISTS test")
cursor.execute("CREATE TABLE test (st TEXT)")
cursor.execute("INSERT INTO test VALUES ('testing')")
cursor.execute("SELECT * FROM test")
print(cursor.fetchall())
cursor.close()
connection.close()
connection2 = sq.connect("test.db")
cursor2 = connection2.cursor()
cursor2.execute("SELECT * FROM test")
print(cursor2.fetchall())

但当我运行它时,它打印了以下内容:

[('testing',)]
[]

它应该打印:

[('testing',)]
[('testing',)]

怎么了？
