Question

我尝试使用python脚本将csv文件中的数据加载到mysql数据库中。当我运行代码时，出现有关字符串的错误。

错误：TypeError：用于格式字符串的参数不足

df = pd.read_csv('testing.csv', delimiter=';', skiprows = 4)
print(df)

for row in df:

 cursor.execute('INSERT INTO FIRMS(ID, \
                REGISTRATION_NUMBER, NAME, DATE_ESTABLISHED, ADDRESS, PHONE_NO, FAX_NO, EMAIL, STATUS, POSTAL_CODE, DISTRICT, STATE )'\
                     'VALUES("%s", "%s", "%s","%s","%s","%s","%s","%s","%s","%s","%s","%s")',
                     row)

df.to_pymysql("FIRMS", db , flavor='pymysql', if_exists='append')
db.commit()
cursor.commit()

是否有解决此问题的建议？谢谢你。

这里的问题是，您正在尝试传递想要元组的列表。应该通过将行强制转换为元组来解决此问题，例如：

cursor.execute('INSERT INTO FIRMS(ID, \
            REGISTRATION_NUMBER, NAME, DATE_ESTABLISHED, ADDRESS, PHONE_NO, FAX_NO, EMAIL, STATUS, POSTAL_CODE, DISTRICT, STATE )'\
                 'VALUES("%s", "%s", "%s","%s","%s","%s","%s","%s","%s","%s","%s","%s")',

                tuple(row))

那应该为您修复

TypeError：格式字符串的参数不足（使用pyhton将数据从csv加载到mysql中）
