What is causing the invalid syntax error in this function?

While doing this excerise of the Python Basics course here on Team Tree house I have run into an error that I can't seem to solve. I keep getting this error when trying to fun the script:

treehouse:~/workspace$ python letter_game.py                                                     
  File "letter_game.py", line 50                                                                 
    if len(guess) !=1:                                                                           
                     ^                                                                           
SyntaxError: invalid syntax  

I have tried multiple things with no success. Here is what the function I actually typed out contains. Maybe I am just missing something really simple.

def get_guess(bad_guesses, good_guesses):
    while True:
        guess = input("Guess a letter: ".lower()

        if len(guess) !=1:
            print("You can only guess single letter!")            
        elif guess in bad_guesses or guess in good_guesses:
            print("You've already guessed that letter!")            
        elif not guess.isalpha():
            print("You can only guess letters!")         
        else:
            return guess

Any help anyone can provide would be greatly appreciated!

You're missing a symbol.

On this line:

        guess = input("Guess a letter: ".lower()

It looks like you're missing a close parenthesis after the string and before .lower. The system doesn't become aware of the error until it reaches the end of the following line.
