How to efficiently hold a key in Pygame?

Question

I\'ve found two related questions:

• Pygame hold key down causes an infinite loop
• pygame - on hold button down

But I want to be specific. H

Answer 1

Dominik's solution is the perfect one (separating event.get() from the keyboard ones). It works perfectly! Finally, no more problems with pygame's input.

Flags:

flag = False # The flag is essential.
while not done:
    for e in event.get(): # At each frame it loops through all possible events.
        keys = key.get_pressed() # It gets the states of all keyboard keys.
        if e.type == QUIT:
            done = True
        if e.type == KEYDOWN: # If the type is KEYDOWN (DIFFERENT FROM "HELD").
            if keys[K_DOWN]: # And if the key is K_DOWN:
                flag = True # The flag is set to true.
        elif e.type == KEYUP: # The very opposite.
            if keys[K_DOWN]:
                flag = False
    if flag == True: # DON'T USE "while flag == true", it'll crash everything. At every frame, it'll check if the flag is true up there. It's important to remember that the KEYDOWN worked ONLY ONCE, and it was enough to set that flag. So, at every frame, THE FLAG is checked, NOT THE KEYDOWN STATE. Every "player movement" while a key is being held MUST be done through flags.
        print "DOWN"
