DBの情報をlistに格納したい

Posted at
import psycopg2
connection = psycopg2.connect("********")
cur = connection.cursor()
list = []#ちなみにこれは作れない
cur.execute("SELECT ID FROM DB;")
list = cur
print(list)

直接入れると無理みたい
curで取得できるのは「[(1),(2),(3)]」でlistの中にtupleが入っているので扱いづらい。ので、listの中にstringで追加した変数を作りたい

import psycopg2
connection = psycopg2.connect("********")
cur = connection.cursor()
list = []
cur.execute("SELECT ID FROM DB;")
for i in cur:
   list.append(str(i[0]))
print(list)

これなら[1,2,3]のように作成されるので扱いやすい
