I'm making a sound pitch study app.

To repeat the program I used 'while and break' statement at first, but it didn't work in the 'scene'.
So I'm trying to use 'Action.repeat()' to repeat program. It works very fine.
And now I want to stop (cancel) the repeat and go back to 'setup(self)' or 'new_play(self)' screen when I touch 'stop_icon' SpriteNode automatically in the middle of the repeat program (when I don't want to repeat them10times (in my program below)).

Please help me achieve it.

from scene import *
import sound
from random import randint
#A = Action

class MyScene (Scene):
    def setup(self):
        self.background_color='#0000ff'
        ground=Node(parent=self)

        icons=['iob:ios7_play_32','iob:ios7_pause_32']

        self.start_icon=SpriteNode(icons[0],position=(self.size.w/2,150))
        self.start_icon.size*=3     

        self.stop_icon=SpriteNode(icons[1],position=(self.size.w/2,150))
        self.stop_icon.size*=3

        self.pmi=self.start_icon
        self.add_child(self.pmi)
        self.play_mode=False

    def did_change_size(self):
        pass    


    def sound_list(self):
        num=randint(0,12)

        sl=['piano:C4','piano:C#4','piano:D4','piano:D#4','piano:E4','piano:F4','piano:F#4','piano:G4','piano:G#4','piano:A4,'piano:A#4','piano:B4','piano:C5']

        self.player=sound.Player(sl[num])
        self.player.play()

    def new_play(self):
        self.pmi.remove_from_parent()
        self.pmi=self.start_icon
        self.add_child(self.pmi)
        self.play_mode=False

    def update(self):   # I don't want to use this update() function.
        pass

    def touch_began(self, touch):
        if self.play_mode==False:
            if touch.location in self.pmi.frame:
                self.pmi.remove_from_parent()
                self.pmi=self.stop_icon
                self.add_child(self.pmi)
                self.play_mode=True
                sq_1=Action.sequence(Action.call(self.sound_list),Action.wait(2.0)) # And more actions continue actually.

                rp_num=10   # I want to stop Action.repeat(sounds) when I touch 'stop_icon', when I don't want to repeat 10times in this case.
                rp=Action.repeat(sq_1,rp_num)

                sq_2=Action.sequence(rp,Action.call(self.new_play))

                self.run_action(sq_2)


        elif self.play_mode==True:  # I want to stop Action.repeat(sounds) when I touch 'stop_icon'(self.pmi), when I don't want to repeat 10times in this case.
            if touch.location in self.pmi.frame:
                self.pmi.remove_from_parent()
                self.pmi=self.start_icon
                self.add_child(self.pmi)
                self.play_mode=False

    def touch_moved(self, touch):
        pass

    def touch_ended(self, touch):
        pass

if __name__ == '__main__':
    run(MyScene(), show_fps=False)

From docs of Action:

Once an action has been added to a Node, it cannot be changed anymore, but you can remove it (and stop the animation) using Node.remove_action() or Node.remove_all_actions().

So, try self.remove_all_actions()

It worked!!
I could stop Action.repeat().
Thank you so much!!
