Psycopg2 INSERT变量，字符串格式错误

Question

I am trying to update a row of a Postgresql table. I am using Psycopg2 and Python3.

I receive the error: "TypeError: not all arguments converted during string formatting"

code: self.cursor.executemany("INSERT INTO blacklisted_ips (ip, source_id, date_created, date_modified) VALUES (%s, %s, %s, %s);", ["address_list"])

ip, source_id, date_created, date_modified are the column names.

passing a list of tuples address_list sample data: ('223.223.202.183', 29, '2018-06-28 12:32:02', '2018-06-28 12:32:02')

I can't figure out why I get this error. I'm guessing it is centered around the place holders after "VALUES". Any help is greatly appreciated.

Assuming address_list is a list of values to be inserted, you can pass it directly to executemany :

self.cursor.executemany("INSERT INTO blacklisted_ips (ip, source_id, date_created, date_modified) VALUES (%s, %s, %s, %s);", address_list)

(Note the lack of quotes and brackets around address_list .)
