Random Choice is out of list range in Python?

I am trying to create a program that will guess the number you entered. I was trying to get the computer to get the number in as few guesses as possible so I am doing something like a binary search. I keep getting a Index out of range when I run the code and it gets to total = total[the_low_one:computer2_guess]. I am confused why it is out of range. Should I be adding or subtracting one to the_low_one each time it hits a new low so it stays in range? I would appreciate any help as I am lost. Thanks a bunch in advance! Code:

def second_computer():
    global computer2_score
    computer2_score=0
    computer2_guess= -1
    the_low_one=1
    the_high_one=1000000
    total= range(1,1000000)
    while computer2_guess != pick_number:
        computer2_guess=random.choice(total)
        if computer2_guess>pick_number:
            total=total[the_low_one:computer2_guess]
            the_high_one=computer2_guess-1
        else:
            total=total[computer2_guess:the_high_one]
            the_low_one=computer2_guess+1
        computer2_score+=1
