Key compination at pygame

I’m using this python code https://gist.github.com/seankmartin/f660eff4787b586f94d5f678932bcd27#file-keyboardpress-py to get time for keyboard events. It’s working well, but I need to get KEYDOWN and KEYUP also for capital letters and exclamation point. So I modified it by adding

elif event.key == key and pygame.key.get_mods() & pygame.KMOD_SHIFT:
    print (f"Pressed SHIFT + key {key_strs[i]} at time {ctr_adj_ms:.0f}ms")

to this part

        if event.type == pygame.KEYDOWN:
            for i, key in enumerate(keys):
                if event.key == key:
                    counters[i] = time.time()
                    ctr_adj = counters[i] - start_time
                    ctr_adj_ms = ctr_adj * 1000
                    time_log.append((key_strs[i], ctr_adj_ms))
                    print(f"Pressed key {key_strs[i]} at time {ctr_adj_ms:.0f}ms")

So now it looks like this

        if event.type == pygame.KEYDOWN:
            for i, key in enumerate(keys):
                if event.key == key:
                    counters[i] = time.time()
                    ctr_adj = counters[i] - start_time
                    ctr_adj_ms = ctr_adj * 1000
                    time_log.append((key_strs[i], ctr_adj_ms))
                    print(f"Pressed key {key_strs[i]} at time {ctr_adj_ms:.0f}ms")
                elif event.key == key and pygame.key.get_mods() & pygame.KMOD_SHIFT:
                    counters[i] = time.time()
                    ctr_adj = counters[i] - start_time
                    ctr_adj_ms = ctr_adj * 1000
                    time_log.append((key_strs[i], ctr_adj_ms))
                    print (f"Pressed SHIFT + key {key_strs[i]} at time {ctr_adj_ms:.0f}ms")

But I still can’t get no capitals letter, no exclamation point. What i’m doing wrong?

Answer

The keyboard events KEYDOWN and KEYUP (see pygame.event module) create a pygame.event.Event object with additional attributes. The key that was pressed can be obtained from the key attribute (e.g. K_RETURN , K_a) and the mod attribute contains a bitset with additional modifiers (e.g. KMOD_LSHIFT). The unicode attribute provides the Unicode representation of the keyboard input. e.g.:

for event in pygme.event.get():

    if event.type == pygame.KEYDOWN:

        if event.key == pygame.K_a:
            if event.mod in [pygame.KMOD_LSHIFT, pygame.KMOD_RSHIFT]:

                # capital 'A'
                # ...
