Database 在数据库中创建多行

我不知道为什么我不能测试我的功能。我想要的输出是ID，然后是Room，但如果同一ID有多个房间，则将其放入新行，如

  ID   Room
  1   SW128 SW 143
  into 
  ID Room
   1  SW128
   1  SW143

这是文件中的一些数据

   1,SW128,SW143
   2,SW309
   3,AA205
   4,AA112,SY110
   5,AC223
   6,AA112,AA206

但我甚至不能测试我的功能。谁能帮我修一下吗

def create_location_table(db, loc_file):
'''Location table has format ID, Room'''

con = sqlite3.connect(db)
cur = con. cursor()
cur.execute('''DROP TABLE IF EXISTS Locations''')
# create the table
cur.execute('''CREATE TABLE Locations (id TEXT, Room TEXT)''')



# Add the rows
loc_file = open('locations.csv', 'r')
loc_file.readline()
for line in loc_file:
    d = {}
    data = line.split(',')
    ID = data[0]
    Room = data[1:]
    for (ID, Room) in d.items():
        if Room not in d:
            d[ID] = [Room]
            for i in Rooms:
                cur.execute(''' INSERT INTO Locations VALUES(?, ?)''', (ID, 
                 Room))
     # commit and close cursor and connection
con.commit()
cur.close()
con.close()

问题是，

d

始终是一个空的dict，因此d.items（）中（ID，Room）的

不会做任何事情。您需要做的是在
房间
上循环。而且您不需要
d
dict

def create_location_table(db, loc_file):
    '''Location table has format ID, Room'''

    con = sqlite3.connect(db)
    cur = con. cursor()
    cur.execute('''DROP TABLE IF EXISTS Locations''')
    # create the table
    cur.execute('''CREATE TABLE Locations (id TEXT, Room TEXT)''')

    # open the CSV
    csv_content = open(loc_file, 'r')

    for line in csv_content:
        data = line.strip().split(',')
        # made lowercase following PEP8, but 'id' is a built in name in python
        idx = data[0]
        rooms = data[1:]
        # loop through the rooms of this line and insert one row per room
        for room in rooms:
            cur.execute(''' INSERT INTO Locations VALUES(?, ?)''', (idx, room))
            # for debug purposes only
            print('INSERT INTO Locations VALUES(%s, %s)' % (idx, room))
    # commit and close cursor and connection
    con.commit()
    cur.close()
    con.close()

# call the method
create_location_table('db.sqlite3', 'locations.csv')

注意：下面我将您的变量设置为小写

编辑：发布完整代码示例，使用
loc_文件
参数
注释不用于扩展讨论；这段对话已经结束。
