So I'm writing a code that imports pygame to play files of music notes. I set each note to a button, 24 notes for 24 buttons. However, the program will also have four more buttons: "Record", "Stop", "Playback", and "Quit". when the record button is clicked, it will append the file name to a songlist. Then the stop button will be pressed to terminate the record function. the songlist will then be played using the playback by having an index = 0 and in the function it will have:

while index < len(songList):
        mixer.init()
        mixer.music.load("C:/Python32/Python Programs/NEW FINAL            PROJECT/notes/"+songList[index])
        mixer.music.play(0,0.0)
        index+=1

The function will go through each element of the list and play each note.


So my problem here, is creating the record function. I need to have it so that it knows when a note button is clicked so that it can append a name to the songlist. So can I write a code that tells whether or not a button is clicked or not.

for example in pseuodocode...

if "C# Button is clicked":
    note = 'Csharp.mp3'
    songList.append(note)
if "D Button is clicked":
    note = 'D.mp3'
    songList.append(note)

how would I write in actual coding ( if "D Button is clicked")

when each note button is pressed, it runs this function:

def playC(self):
        mixer.init()
        mixer.music.load("C:/Python32/Python Programs/NEW FINAL PROJECT/notes/"+NOTELIST[0])
        mixer.music.play(0,0)
        note = '2C.mp3'

Each note button will have this format but with the note and the filename different of course. a friend of mine gave me the idea to set maybe a dummy statement such as
self.C = 'Go' after the mixer.music.play function. So that I would write in the Record function....
if self.C = 'Go':
songList.append(note)

Any ideas? this is the actual code that I have so far... it's not quite finished yet and I've been commenting stuff out as well.

Do not repeat code but use loop and argument with value from notelist by functools.partial.

This code wont run as you have place holder functions without any statements, add pass statement. Record/Stop should be toggle switch changing the self.recording between True and False. Add self.recording check into play function. You should probably use key up even to record the length of note. Also you should assoociate keyboard key so you possibly can push chords, even keyboard keys are not so reliable with multiple keys pressed (in same loop you associate the graphical button)

Here textual way worked on code (as I have not mp3 files).

I need to have it so that it knows when a note button is clicked

The standard way is to set some variable. In Tony's code, a button click calls play_note() and sends it the note and key. You could use the key to tell which button is clicked and possibly link it to a dictionary that contains the function you want to execute.

I am saving clock time with note information and checking it whe key goes up. My newer version has multiple keypresses OK by keeping set of currently playing keys/mouse presses. Note and key are of course redundant, but now I finally needed the key_note dictionary also. The redundancy can be cleaned at end but it is usefull until code is finalized. Even nowadays it is not so big sin to waste memory for dictionary of all of 24 values... Sometimes my 64 kByte memory days...
