# Bug in code showed in the video

If you run the game and enter a letter(or something that is not an integer) as your first guess, you get a syntax error.

Try downloading the code, run the game and enter a letter.

What error do you get? are you running locally in Python2 or Python3?

Traceback (most recent call last):
File "number_game.py", line 27, in <module>
game()
File "number_game.py", line 15, in game
print("{} isn't a number!".format(guess))
UnboundLocalError: local variable 'guess' referenced before assignment

That's what I've been getting, here's my code:

```import random

def game():
#generate a random number between 1 and 10

secret_num = random.randint(1,10)
guesses = []

while len(guesses) < 5:
try:
#get a number guess from the player
guess = int(input("Guess a number between 1 and 10: "))

except ValueError:
print("{} isn't a number!".format(guess))

else:

if guess == secret_num:
print("You got it, way to go!!")
break

else:
print("That's not it, try again...")
guesses.append(guess)

game()
```

The guess variable isn't being set when you enter something other than an int. Set the variable first, then try to convert it to an int. Like this:

```guess = input("Guess a number between 1 and 10: ")

try:
guess = int(guess)
except ValueError:
print("{} is not an acceptable value".format(guess))
continue
```

The print() function is probably where the error getting thrown. When you try to format guess into the string, python couldn't find a variable with that name because it didn't bother storing the value in memory once it realized it can't be converted to an int.
