Ожидаемое значение Out, если случайное число равно системе 51, и мы нажали 50, оно напечатается слишком низко, а затем продолжим этот процесс. Допустим, мы дали на вход 51 вывод: you got in 2 guesses

isdigit() - строковый метод, он не работает на int входах.

измените это: 

guess = int(input('enter a num'))

на это: 

guess = input('enter a num')

ваш код после редактирования: 

#Guess the num
import random
def is_valid_num(num):
    if num.isdigit() and 1 <= int(num) <= 100:
        return True
    else:
        return False

def main():
    number = random.randint(1,100)
    guessed_number = False
    guess = input('enter a num')
    #guess = (input('enter a num'))
    num_of_guesses = 0
    while not guessed_number:
        if not is_valid_num(guess):
            #return False
            guess = input('i count only digits enter 1<num<100')
            continue
        else:
            num_of_guesses += 1
            break

    guess = int(guess)
    if guess < number:
        print ('entered number is low')
    elif guess > number:
        print ('entered number is high')
    else:
        print ('you got in',num_of_guesses, 'guesses')
        guessed_number = True
main()

@Thanks Issac Full code is below

#Guess the num
import random
def is_valid_num(num):
    if num.isdigit() and 1 <= int(num) <= 100:
        return True
    else:
        return False

def main():
    number = random.randint(1,100)
    guessed_number = False
    guess = input('enter a num')
    #guess = (input('enter a num'))
    num_of_guesses = 0
    while not guessed_number:
        if not is_valid_num(guess):
            #return False
            guess = input('i count only digits enter 1<num<100')
            continue
        else:
            num_of_guesses += 1
            #break

            guess = int(guess)
        if guess < number:
            guess = (input('entered number is low try again'))
        elif guess > number:
            guess = (input('entered number is high try again'))
        else:
            print ('you got in',num_of_guesses, 'guesses')
            guessed_number = True
main()
