如何使用Python将CSV字符串加载到MySQL中

Question

In my use case, I have a csv stored as a string and I want to load it into a MySQL table. Is there a better way than saving the string as a file, use LOAD DATA INFILE, and then deleting the file? I find this answer but it's for JDBC and I haven't find a Python equivalent to it.

Yes what you describe is very possible! Say, for example, that your csv file has three columns:

import MySQLdb
conn = MySQLdb.connect('your_connection_string')
cur = conn.cursor()
with open('yourfile.csv','rb') as fin:
    for row in fin:
        cur.execute('insert into yourtable (col1,col2,col3) values (%s,%s,%s)',row)
cur.close(); conn.close()
