sqlite3.Warning: You can only execute one statement at a time

I get the error when running this code:

import sqlite3

user_name = raw_input("Please enter the name: ")
user_email = raw_input("Please enter the email: ")

db = sqlite3.connect("customer")
cursor=db.cursor()

sql = """INSERT INTO customer
        (name, email) VALUES (?,?);, 
        (user_name, user_email)"""

cursor.execute(sql)

Why is this happening?
