Python referenced before assignment error

I am trying to make a hangman game with pygame. The game itself is irrelevant for this. I defined a variable early on in my code, then later, when a function is called that uses the variable, Python returns a "UnboundLocalError: local variable 'guessedLetters' referenced before assignment" Both the function and the call are later in my code than the variable assignment. This is the variable assignment: guessedLetters = "".

This is the function:

def guess(letter):
    if letter in word:
        pass
    else:
        guessedLetters += '  ' + letter
        hangmanStage += 1

This is where it is called(which is within another method):

def redrawWindow():
    win.fill((150, 150, 150))
    drawLetters()
    drawGuessedLetters()
    drawHangman()

And this is where that method is called

while running:
    for event in ...
    redrawWindow()
    pygame.display.update()

guessedLetters should be declared inside the function if use is local or outside if it is global.

In first case, if it is declared outside function, add a global guessedLetters before referencing to it.

If it is local then add guessedLetters = '' on top.

Do this for other variables like hangmanStage too.
