我是通过看数据库里面数据确认的。代码比较类似，就这么多
#!/usr/bin/python
from MySQLdb import connect
conn = connect(db="test", user="root", host="localhost", unix_socket="/var/lib/mysql/mysql.sock")
cur = conn.cursor()
sql_insert = "insert into test_table(id,name) values('6','f')"
sql_update = "update test_table set name='A' where id ='1'"
sql_delete = "delete from test_table where id>'4'"
conn.autocommit(False)
try:
cur.execute(sql_insert)
print cur.rowcount
cur.execute(sql_update)
print cur.rowcount
cur.execute(sql_delete)
print cur.rowcount
except Exception as e:
print e
conn.rollback()
cur.close()
conn.close()
