Database lock SQlite when going through python for loop

I have a weird issue with my database getting locked on running the following for loop. If I take the 4 function calls out of the loop it and run it they do not lock my database.... I have triple checked to make sure I close the database at the end of each function call so I am wondering if the for loop is not waiting for the functions to be done before the next iteration... If that is what is going on how do I make it wait?

Thanks for all your help guys!

        c.execute("SELECT playerName FROM player")
        for row in c:
            for username in row:
                PaytheBets.PaytheHops(die1, die2, username)
                PaytheBets.PaytheField(theroll, username)
                PaytheHouse.RemoveThePass(username)
                PaytheHouse.RemoveHops(username)
