How to return a specific list from the record in a table?
Write a function named "filtered_records" that doesn't take any parameters and returns a list. There is a database saved in a file named "solar.db" containing a table named "worry" with columns "hip", "log", and "convention" each storing integer values. Return a list containing each record in the table with a "log" value greater than 59.
import sqlite3
def filtered_records():
conn = sqlite3.connect('solar.db')
c = conn.cursor()
confirm_list = c.execute('SELECT log FROM worry').fetchall()
return [list(i) for i in confirm_list if i > 59]
conn.commit()
Here is my attempt at the problem. What am I doing wrong?
python database list sqlite

You have to filter your query in sql. Moreover you don't need to call commit when you just select rows from database, you should use commit function only when you want to insert data to database, here you can read more about transactions
import sqlite3
def filtered_records():
conn = sqlite3.connect('solar.db')
c = conn.cursor()
confirm_list = c.execute('SELECT hip, log, convention FROM worry WHERE log > 59').fetchall()
return confirm_list
