Guessing algorithm does not seem to work, guessing number by Python

Question

I am struggling with some simple algorithm which should make python guess the given number in as few guesses as possible. It seems to be running but it is extremely slow. What a

Answer 1

Apart from having the logic backwards, you should not be using min and max as variable names. They are python functions. You can also use while True and break as soon as the number is guessed.

while True:
    guess = (mn + mx) // 2
    total += 1
    if guess == number:
        print("The number has been found in {} guesses!".format(total))
        break
    elif guess < number:
        mn = guess
    elif guess > number:
        mx = guess

You will also see by not adding or subtracting 1 from guess this will find the number in less steps.

Answer 2

from random import randint

print('choose a number in your brain and if guess is true enter y else any key choose time of guess: ')

print("define the range (A,B) :")
A = int(input("A: "))
B = int(input("B: "))
time = int(input("time:"))

while time != 0:
    ran = randint(A, B)
    inp = input(f"is this {ran} ?")
    time -= 1
    if inp == "y":
        print("bla bla bla python wins!")
        break
    print("NOPE!")
    if time == 0:
        print("computer game over!")
        break

Answer 3

Your logic is backwards. You want to lower the max when you guess too high and raise the min when you guess too low. Try this:

if guess == number:
    print("The number has been found in ",total," guesses!")
    guessed = 1
elif guess > number:
    max = guess - 1
elif guess < number:
    min = guess + 1
