Python MYSql.connector不会插入数据

我想将一些数据插入到我正在创建的数据库中，并且不会插入。我在其他代码中使用相同的插入方法，它似乎仍然有效，但是这个拒绝。帮帮我！Python MYSql.connector不会插入数据

from Bio import Entrez 
from sys import exit 
Entrez.email = "[email protected]"  # Always tell NCBI who you are 
sranumber = raw_input("Input SRA number here") 
sranumber2= raw_input("re-type SRA number here") 
while True: 
    if sranumber != sranumber2: 
     print "SRA numbers do not match" 
     sranumber2 = raw_input("Please re-type sra number to match intitial sra number") 
     continue 
    else: 
     break 
print "SRA ID:" + sranumber 
#answer = raw_input("Are you sure this is the sra number you wish to use? Type Y/N") 
while True: 
    answer = raw_input("Are you sure this is the sra number you wish to use? Type Y/N") 
    if answer == "Y": 
     print "Let's do it!" 
     break 
    elif answer == "y": 
     print "Let's do it!"

您是否收到任何错误？如果你使用'INSERT INTO'而不是'INSERT IGNORE INTO'呢？ – alecxe

（'Error：'，ProgrammingError（））这是我得到的唯一错误。并且insert into与插入忽略有相同的问题。此表中也没有外键，但一个属性被引用为外键。 – george135

我最终只是这样做，它终于奏效了。我不确定为什么它以前没有工作，但我相信它与我在列中输入的格式有关。

from mysql.connector import MySQLConnection, Error 
from python_mysql_dbconfig import read_db_config 

cnx = mysql.connector.connect(user='root',password='*****',database = 'new') 
cursor = cnx.cursor() 
addstuff= ("INSERT IGNORE INTO experiment (`sra`, `condition`) VALUES(%s,%s)") 
cursor.execute(addstuff,stuff3) 
cnx.commit() 
cursor.close() 
cnx.close()
