How do I make text appear letter by letter in a box in Pygame?

Question

So I need a way to make a text box with text that appears letter by letter (like ones you see in Undertale, Earthbound, and many more RPGs). I was wondering how I could do that in Pygame (I dont have code I just need help with how I would be able to do this)

See Typewriter Effect Pygame. The basic idea is that you use a timer event (pygame.time.set_timer()) and append the text letter by letter:

typewriter_event = pygame.USEREVENT+1
pygame.time.set_timer(typewriter_event, 100)

text = 'Hello World'
typewriter_text = ""

while run:
    # [...]

    for event in pygame.event.get():
        if event.type == typewriter_event:
            if len(typewriter_text) < len(text):
                typewriter_text += text[len(typewriter_text)]

Unfortunately pygame cannot render text with line breaks. You have to render the test line by line. See Rendering text with multiple lines in pygame
