使用 python 循環將數據插入 sql 表

Question

我寫了一個 web 抓取代碼來從一個到目前為止工作的網站獲取一些數據。 我將Python連接到SQL因為我需要保存數據MySQL 。 The connection between Python and SQL is working fine, I created the SQL table with Python which I commented on the code below. 我的問題是在將數據插入SQL表時，插入腳本應該可以正常工作，但是我遇到了無法糾正的語法錯誤。 有人有想法嗎？

這是代碼：

import mysql.connector
db_connection = mysql.connector.connect(
host="141.45.91.40",
user="s0566293",
passwd="*******",
database="s0566293_projekt"
)
db_cursor = db_connection.cursor()
#Here creating database table as film'
#db_cursor.execute("CREATE TABLE Filme (filmName VARCHAR(255))") #already exists.

#Get database table'
db_cursor.execute("SHOW TABLES")
for table in db_cursor:
    print(table)
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup
import requests
import re

my_url = 'https://www.berlin.de/kino/_bin/azfilm.php'

# opening up connection , grabbing the page
uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()

#html parsing
page_soup = soup(page_html,"html.parser")

# grab any Zeichen 
az = page_soup.findAll("div",{"class":"block"})
fil = az[0]
sei = fil.findAll("li")


for s in sei:
    i=s.text
    if (i == '#'):
        continue
    else:
        seite = "https://www.berlin.de/kino/_bin/azfilm.php/de/{}".format(i)
        r = requests.get(seite)
        seiten_soup = soup(r.content, 'html.parser')
        #print page url
        #print("-------------------------------------------------------\n" + seite)
    #Filme jeder Seite

    # opening up connection , grabbing the page
        uClient = uReq(seite)
        page_html = uClient.read()
        uClient.close()

    #html parsing
        page_soup = soup(page_html,"html.parser")

    # grab any film
        az = page_soup.findAll("div",{"class":"inner"})
        fil = az[0]
        filme = fil.findAll("li")
        for film in filme:

                db_cursor.execute("INSERT INTO Filme(filmName) VALUES("+film.contents[0].contents[0]+")")
                db_cursor.execute("SHOW Filme")
                #print(film.contents[0].contents[0])

Answer 1

連接變量時，您不會在名稱周圍加上引號。

但是你不應該將變量連接到 SQL，你應該使用占位符。

db_cursor.execute("INSERT INTO Filme(filmName) VALUES(%s)", (film.contents[0].contents[0],))
