I want to insert tables with variable lengths into an sqlite database but I am getting an error stating: Incorrect number of bindings supplied

Because I want to insert tables with varying sizes I need to be able to use a string variable in my insert statement for example like so:

numvals = '?,?'
vals = 'delays_values[0], delays_values[1]'
converted_valz = 'ID int ,Description text'

c.execute("CREATE TABLE DELAYS ("+converted_valz+")")
c.execute("INSERT INTO DELAYS VALUES ("+numvals+" )", (vals))

However this gives me the aforementioned error which says exactly: sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 19, and there are 349 supplied.

For some reason, if I replace vals with the hardcoded values it actually contains like so it actually works but then I am forced to hardcode values which defeats the purpose of all of this. Please help!:

numvals = '?,?'
vals = 'delays_values[0], delays_values[1]'
converted_valz = 'ID int ,Description text'

c.execute("CREATE TABLE DELAYS ("+converted_valz+")")
c.execute("INSERT INTO DELAYS VALUES ("+numvals+" )", (delays_values[0], delays_values[1]))

import sqlite3
conn = sqlite3.connect('example.db')

c = conn.cursor()

delays_values = (1,2)

numvals = '?,?'
vals = 'delays_values[0], delays_values[1]'
converted_valz = 'ID int ,Description text'

c.execute("CREATE TABLE DELAYS ("+converted_valz+")")

c.execute("INSERT INTO DELAYS VALUES ("+numvals+" )", eval(vals))
