Python 3.x 美化组导致字典存储到数据库

我正在抓取一个网站，并将结果存储在嵌套字典中。 字典的结构与我的数据库相同。 我的目标是编写一个带有一个参数的函数，该参数保存表名并将字典中的数据插入该表中

我有以下代码

url = requests.get("http://www.randomurl.com")
data = url.text
soup = BeautifulSoup(data, "html5lib")

cnx = pymysql.connect(host='localhost',
                  user='root',
                  password='',
                  database='mydb')

cursor = cnx.cursor()

band = {    
            "band_info":    {
                            "band_name" : soup.find('h1', {'class': 'band_name'}).get_text(),
                            "band_logo" : soup.find('a', {'id': 'logo'})['href'],
                            "band_img" : soup.find('a', {'id': 'photo'})['href'],
                            "band_comment" : soup2.find('body').get_text().replace('\r', '').replace('\n', '').replace('\t', '').strip()
                            },
            "countries":    {
                            "country" : "value",
                            },
            "locations":    {
                            "location" : "value",
                            },
            "status":       {
                            "status_name" : "value",
                            },
            "formedin":     {
                            "formed_year" : "value",
                            },
            "genres":       {
                            "genre_name" : ["value","value","value"]
                            },
            "lyricalthemes":{
                            "theme_name" : ["value","value","value"]
                            },
            "labels":       {
                            "label_name" : ["value","value","value"]
                            },
            "activeyears":  {
                            "active_year" : "value"
                            },
            "discography":  {
                            "album_name" : ["value","value","value"]
                            },
            "artists":      {
                            "artist_name" : ["value","value","value"]
                            }
        }

def insertData(table):
    placeholders = ', '.join(['%s'] * len(band[table]))
    columns = ', '.join(band[table].keys())
    values = band[table].values()
    sql = "INSERT INTO %s ( %s ) VALUES ( %s )" % (table, columns, placeholders)
    print(sql)
    cursor.execute(sql, values)


insertData("band_info")

cursor.close()
cnx.close()

字典“band”中的第一个键的命名与数据库中的表类似。嵌套键是该表中的列。我编写的函数将根据它得到的参数插入正确的值

我得到这个错误：

Traceback (most recent call last):
File "parser.py", line 144, in <module>
insertData("band_info")
File "parser.py", line 141, in insertData
cursor.execute(sql, values)
File "\Python\Python36-32\lib\site-packages\pymysql\cursors.py", line 164, in execute
query = self.mogrify(query, args)
File "\Python\Python36-32\lib\site-packages\pymysql\cursors.py", line 143, in mogrify
query = query % self._escape_args(args, conn)
File "\Python\Python36-32\lib\site-packages\pymysql\cursors.py", line 129, in _escape_args
return conn.escape(args)
File "\Python\Python36-32\lib\site-packages\pymysql\connections.py", line 814, in escape
return escape_item(obj, self.charset, mapping=mapping)
File "\Python\Python36-32\lib\site-packages\pymysql\converters.py", line 27, in escape_item
val = encoder(val, mapping)
File "\Python\Python36-32\lib\site-packages\pymysql\converters.py", line 110, in escape_unicode
return u"'%s'" % _escape_unicode(value)
File "\Python\Python36-32\lib\site-packages\pymysql\converters.py", line 73, in _escape_unicode
return value.translate(_escape_table)
AttributeError: 'dict_values' object has no attribute 'translate'

我得到了一个非常相似的错误代码，但我无法找出数据类型的错误：

query = query % self._escape_args(args, conn)
TypeError: not all arguments converted during string formatting

---

如前所述，我试图编写列表（值，值），但我得到了相同的错误。

问题是在

execute（）

的第二个参数上传递

dict\u值。
value
只接受元组、列表或dict。您可以尝试以下操作：

def insertData(table):
    placeholders = ', '.join(['%s'] * len(band[table]))
    columns = ', '.join(band[table].keys())
    values = list(band[table].values()) # I edited this part
    sql = "INSERT INTO %s ( %s ) VALUES ( %s )" % (table, columns, placeholders)
    print(sql)
    cursor.execute(sql, values)

您在
execute（）
中传递了错误的数据类型，能否提供正确的URL，以便我检查您的代码逻辑。谢谢你好，查德，谢谢你的回复。我正在努力抓取以下网址：太棒了！谢谢我更新了我的问题，因为我在继续下一个问题时遇到了相同的错误。将关系插入到另一个表中。您可以进一步帮助？
？
应该是
%s
很好，现在它说“您的SQL语法有一个错误；请检查与您的MariaDB服务器版本对应的手册，以获得在第2行“WHERE band_logo=”附近使用的正确语法，因为
WHERE band_name=？”？乐队logo=？
你有两个应该是
乐队名称=？和band_徽标=？
def insertData(table):
    placeholders = ', '.join(['%s'] * len(band[table]))
    columns = ', '.join(band[table].keys())
    values = list(band[table].values()) # I edited this part
    sql = "INSERT INTO %s ( %s ) VALUES ( %s )" % (table, columns, placeholders)
    print(sql)
    cursor.execute(sql, values)
