8,897 PointsValuerError: invalid literal for int() with base 10: '' meaning?
So, this is my code:
# generate a random number between 1 and 10
secret_num = random.randint(1, 10)
while True:
# get a number guess form the player
guess = int(input("Guess a number between 1 and 10: "))
# compare guess to secret number
if guess == secret_num:
print("Your guess is correct! My number was {}".format(secret_num))
break
else:
print("Ups, your guess is incorrect! Try again!")
continue
The only difference between what Kenneth wrote and what I wrote is that I added "continue" in the else statement. I repeatedly entered number 5 in order to guess the name and after a few times I got this error:
"ValuerError: invalid literal for int() with base 10:"
The program stopped working afterwards. Does anyone know what does it mean and why I got this error?

ValueError: invalid literal for int() with base 10: '' At the end of my error is an empty string, when I enter + I got : ValueError: invalid literal for int() with base 10: '+'. I hope this helps find what happened.

The "continue" at the end is not needed, but doesn't cause any issues.
