Reverse Numbers game help

I need help with the reverse numbers game. Below is the code I have so far

import random

secret_num = random.randint(1, 10)
def second_choice():
    second_choice = random.randint(1, 10)


def game():
    guesses = []
    while len(guesses) < 5:
        print(secret_num)
        guesses.append(secret_num)
        guess_again = input("Did I get your number right? Y/n. ")
        if guess_again == 'y':
            print("You got it")
            break
        elif guess_again == 'too high':
            print('I will choose a higher number')
            second_choice()

I cannot figure out how to get my computer to guess again and guess a different number and not repeat one he has already guessed.

So now I am at a point where I can't get the computer to guess a different number each try. But I am having trouble limiting the computer to 5 tries. Also getting it to guess higher or lower than the previous guess.

I very simple way would be to add an input question "do you want to continue" after the while loop. If Yes, then simply call game() to restart.

This has the minor drawback that this is a recursive call (game() calling game()) which does have a compiler limit of ~1000 so after 1000 games it might crash with a RecursionError: maximum recursion depth exceeded. This is acceptable for this level of coding.

so I've gotten to that point. but the computer keeps guessing the same number. How can I tell it to guess higher or lower

            play_again = input("Do you want to play again? Y/n ")

        elif guess_again.lower() == 'n':
            game()


game()

It looks like you're not saving the guesses.

  • Save randint result in variable guess
  • add `guesses.append(guess)
  • print guess
  • adjust the guess by replacing the arguments of the randint with (last_too_low, last_too_high)
  • add code to track last_too_low and last_too_high
  • you will need to adjust the feedback from the user to know if guess was too high or low

Ok That sounds great! But I don’t think I learned how to do any of that so far. Mind walking me through?

It might be better to revisit this after getting farther along in the coursework.
