IndexError: Index out of range Python Error

My Code:

def email_address_grab(email_list):

""" This function takes in a list of emails and puts them into a sql database """


#import module
import sqlite3 as sql


#Setup sql
#create connection for sql
connection = sql.connect("emailList.db")

#create cursor
crsr = connection.cursor()

 #create sql table
cmd = """CREATE TABLE emails (
email_handle TEXT,
email_domain VARCHAR(20));"""
crsr.execute(cmd)


#iterate through email list
index = 0
for email in email_list:
    #split email with a delimiter of "@"
    email_list[index] = email.split('@')
    index += 1

#while loop to put all data into table
ct = 0
index = 0
while ct <= (len(email_list) - 1):
    for i in email_list:
        for j in email_list:
            email_address_1 = email_list[index]
            email_address_2 = email_list[index + 1]
            cmd = f"""INSERT INTO emails (email_handle, email_domain)
            VALUES ({email_address_1}, {email_address_2});"""
            crsr.execite(cmd)
            index += 1
    ct += 1


#get the contents of the table
crsr.execute("SELECT * FROM emails;")

#store contents in a variable
email_address_list = crsr.fetchall()

#save changes to sql table
connection.commit()

#close connection
connection.close()


#return print statement for data
return print(email_address_list)

I am getting an IndexError:

File "c:/Users/USER/Desktop/email grabber.py", line 82, in
email_address_grab(["[email protected]"])

File "c:/Users/USER/Desktop/email grabber.py", line 57, in email_address_grab
email_address_2 = email_list[index + 1]

IndexError: list index out of range

How can I fix this?

email_address_1 = email_list[i]
email_address_2 = email_list[j]
