Inserting in sqlite with each thread in Python

I am trying to insert in a SQLITE database the new response I get from my API on each thread for 3 different cities. However I get an error on the execute command as I seem to be unable to insert the values as a weather['main']['temp'] or even if I give it to a variable y = weather['main']['temp'] it still doesn't work. I would welcome any suggestions

import requests
import json
import threading
import time
from threading import Thread
import sqlite3
conn = sqlite3.connect("dfg.db",check_same_thread = False)
c = conn.cursor()

def main():
    createT()
    threading.Timer(10, giveVelingrad).start()
    threading.Timer(15, giveSofia).start()
    threading.Timer(25, givePlovdiv).start()

def createT():
        c.execute('CREATE TABLE IF NOT EXISTS tabl(city TEXT, temp REAL)')    

def giveVelingrad():
    city = "Velingrad"
    response = requests.get("http://api.openweathermap.org/data/2.5/weather?q=" +city+ "&appid=2e8707d1eb97fbbba33ef766d9ed80ac&units=metric")
    weather = response.json()
    www = time.strftime("%d.%m.%y %H.%M.%S")
    y = weather['name']
    z = weather['main']['temp']
    c.execute("INSERT INTO tabl VALUES (?, ?)",y,z )
    conn.commit()
    c.close()
    conn.close()
    print("\n",www)
    print("The weather for ", weather['name'])
    print("The temperature is ", weather['main']['temp'])

def giveSofia():
    city = "Sofia"
    response = requests.get("http://api.openweathermap.org/data/2.5/weather?q=" +city+ "&appid=2e8707d1eb97fbbba33ef766d9ed80ac&units=metric")
    weather = response.json()
    www = time.strftime("%d.%m.%y %H.%M.%S")
    print("\n",www)
    print("The weather for ", weather['name'])
    print("The temperature is ", weather['main']['temp'])

def givePlovdiv():
    city = "Plovdiv"
    response = requests.get("http://api.openweathermap.org/data/2.5/weather?q=" +city+ "&appid=2e8707d1eb97fbbba33ef766d9ed80ac&units=metric")
    weather = response.json()
    www = time.strftime("%d.%m.%y %H.%M.%S")
    print("\n",www)
    print("The weather for ", weather['name'])
    print("The temperature is ", weather['main']['temp'])

    main()
