Can't work out what's wrong

Hi there. My code generates a syntax error.

import random

# safely create an integer
# limit number of guesses
# "too high" message
# "too low" message
# play again

def game():
    # generate random number between 1 and 100
    secret_num = random.randint(1, 10)
    num_of_guesses = []

    while len(num_of_guesses) < 5:
        try:
            # get number guess from player
            guess = int(input("Guess a whole number between 1 and 10. "))
        except ValueError:
            print("{} isn't a number.".format(guess))
        else:
            # compare guess to secret number
            if guess == secret_num:
                print("Well done! My number was: {}".format(secret_num))
                break
            elif guess < secret_num:
                print("Higher than {}".format(guess))
            else:
                print("Lower than {}".format(guess))
            num_of_guesses.append(guess)

    else:
        print("Bad luck! My number was {}".format(secret_num))
    play_again = input("Do you want to play again? Y/n"
    if play_again.lower() != "n": # Error on this line
        game()
    else:
        print("Thanks for playing. Bye!")

Can someone please tell me what's wrong?

Thanks

Sean

Hi Sean,

Yeah, it's okay. It will run the game should user decide to go ahead and play again.

The game() will just make it work for the first script run.

Hope this helps.

Art.

Hi Art.

I did as you said and the program works now. I can't understand why Kenneth didn't need to add game() twice, like I did, though when I unindented line 31 and everything below it and pressed Enter, the cursor was over-indented (too far to the right).

But I do appreciate your assistance.

Thank you

Sean :-)

Your input does not have a closing parenthesis. )

Just as mentioned above - the problem is here:

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

Hi guys. Thanks for your efforts to help.

import random

# safely create an integer
# limit number of guesses
# "too high" message
# "too low" message
# play again

def game():
    # generate random number between 1 and 10
    secret_num = random.randint(1, 10)
    num_of_guesses = []

    while len(num_of_guesses) < 5:
        try:
            # get number guess from player
            guess = int(input("Guess a whole number between 1 and 10. "))
        except ValueError:
            print("{} isn't a number.".format(guess))
        else:
            # compare guess to secret number
            if guess == secret_num:
                print("Well done! My number was: {}".format(secret_num))
                break
            elif guess < secret_num:
                print("Higher than {}".format(guess))
            else:
                print("Lower than {}".format(guess))
            num_of_guesses.append(guess)

    else:
        print("Bad luck! My number was {}".format(secret_num))
    play_again = input("Do you want to play again? Y/n ") # Closing parenthesis 
    if play_again.lower() != 'n':
        game()
    else:
        print("Thanks for playing. Bye!")

Now the program won't run at all. No error message or anything. I'm not sure what to do.

Sean, you need to run it. The script just defining the function.

Try adding this to the end of the script:

game()

Hi artkay.

So I should add game() to the end of the script, even though it's already under the line if play_again.lower() != 'n': ?

Thanks.

Sean
