tomorrow --------- binary search I guess :)

import random
import math

high = 10000

secret = random.randint(1, high)
# secret = 99

seq = ''

rounds = math.ceil(math.log2(high))

print(f"Range is 1 to {high}")

for n in range(1, rounds + 1):
    guess_input = input("Guess! ")
    guess = int(guess_input)
    if guess > secret:
        print("too high!")
        seq += '0'
    elif guess < secret:
        print("too low!")
        seq += '1'
    else:
        print("win!")
        seq += '1'
        seq += (rounds - n) * '0'
        break

print(seq)
print(int(seq, 2))
