Question

所以在这里我试图将csv文件'employee_reviews.csv'的值存储到我的雇员表中。我正在读取文件，将其存储为字符串，然后将元素一路拆分为2D列表，然后将其循环遍历每一行。我敢肯定，这样做有更简单的方法。运行代码时，出现错误->

cur.execute（“ INSERT INTO（id，company，location，date，job_title，摘要，优点，缺点，advice_to_management，总体评分， work_balance_stars，culture_value_stars，career_opportunities_stars， comp_benefit_stars，senior_management_stars，有用计数，链接）价值（％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％s，％ s）“，（int（row [0]），行[1]，行[2]，行[3]，行[4]，行[5]，行[6]，行[7]，行[8]， int（row [9]），第[10]行，第[11]行，第[12]行，第[13]行，第[14]行， int（row [15]），row [16]））ValueError：int（）的无效文字以10为基数：“无”

import csv
import MySQLdb

mydb = MySQL.connect(host="host",user="user",passwd="passwd",db="Employee_Review")
cur = mydb.cursor()
#cur.execute("CREATE TABLE employees(id INT, company VARCHAR(20), location VARCHAR(40), dates DATE, job_title VARCHAR(20), summary VARCHAR(50), pros VARCHAR(1000), cons VARCHAR(1000), advice_to_management VARCHAR(50), overall_ratings INT, work_balance_stars VARCHAR(10), culture_value_stars VARCHAR(10), career_opportunities_stars VARCHAR(10), comp_benefit_stars VARCHAR(10), senior_management_stars VARCHAR(10), helpful_count INT, link VARCHAR(75) )")

f = open("employee_reviews.csv","r")
fString = f.read()

fList = []
for line in fString.split('\n'):
   fList.append(line.split(','))

for row in fList:
   if row == fList[0]:
      continue #skip the first row for it contains the name of the columns

   cur.execute("INSERT INTO (id, company, location, dates, job_title, summary, pros, cons, advice_to_management, overall_ratings, work_balance_stars, culture_value_stars, career_opportunities_stars, comp_benefit_stars, senior_management_stars, helpful_count, link) VALUES (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)",(int(row[0]), row[1], row[2], row[3], row[4], row[5], row[6], row[7], row[8], int(row[9]), row[10], row[11], row[12], row[13], row[14], int(row[15]), row[16] ))
   mydb.commit()

mydb.close()

CSV中的一个值是“ none”，无法在其中一个整数列中将其转换为整数。
