我在让数据库和webiopi一起工作时遇到了一些问题。我已经在导入sqlite3和更改文件夹权限,但是当我运行时,没有创建任何内容。但是,其他功能在f.write('This is a test\n')后,每个进程正常工作并重复循环。希望你能帮我?
def loop():
db = sqlite3.connect('schedule.db')
db.execute('DROP TABLE IF EXISTS schedule')
db.execute('CREATE TABLE schedule (hour int, minute int, second int, status text)')
db.execute('INSERT INTO schedule (hour,minute,second,status) VALUES (?,?,?,?)',(sche.get('hour'),sche.get('minute'),sche.get('second'),"yes"))
db.commit()
f = open('workfile', 'w')
f.write('This is a test\n')
loop1=1
while ((now.minute >= minute_ON) and (now.minute < minute_OFF) and (loop1<stepping)):
step()
loop1=loop1+1谢谢

对于数据库,您可以更好地使用游标和conn。有关更多信息,请参见文档。
对于文件,当您不将它用于写数据时,可以使用close()。下面的代码可能有助于:
def loop():
db = sqlite3.connect('schedule.db')
cur = db.cursor() # create a cursor
cur.execute('DROP TABLE IF EXISTS schedule')
cur.execute('CREATE TABLE schedule (hour int, minute int, second int, status text)')
cur.execute('INSERT INTO schedule (hour,minute,second,status) VALUES (?,?,?,?)',(sche.get('hour'),sche.get('minute'),sche.get('second'),"yes"))
db.commit()
cur.close() # close cursor
db.close() # close connection to sqlite3
f = open('workfile', 'w')
f.write('This is a test\n')
f.close() # close file to write data
loop1=1
while ((now.minute >= minute_ON) and (now.minute < minute_OFF) and (loop1<stepping)):
step()
loop1=loop1+1https://stackoverflow.com/questions/28123371
