Registering keypress when no key has been pressed(recently)

Question

Ok, maybe I'm missing something about the way PyGame registers input.

My problem is when the snooze() method leaves it's audio loop and calls alarm(getup_file) or alarm(alarm_file), it enters the alarm() audio loop and then immediately calls snooze() again without any keys being pressed. This only occurs if I have already hit the space bar during the initial audio loop calling snooze() at some point but not if I start with a call to snooze() initially never having the space bar pressed.

Here is my simple alarm script.

#!/usr/bin/env python3

import schedule, subprocess, time, os, sys
import pygame as pg


if len(sys.argv) > 1:
    x = int(sys.argv[1]) - 140
    y = int(sys.argv[2]) - 190
    os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (x,y)
else:
    x=50
    y=50
    
pg.init()
pg.display.set_mode((100,100))

alarm_file = "/home/pi/Alarm/keelhauled.mp3"
getup_file = "/home/pi/Alarm/witness.mp3"
dream_track = "/home/pi/Alarm/dreamtrack.mp3"
snoozed = 0
volume = 0.08

def get_up():
    currentTime = (int(time.strftime("%H", time.localtime())) * 100) + (int(time.strftime("%M", time.localtime())))

    if currentTime > 650:
        return True

def snooze():
    global snoozed
    snoozed += 1
    #time.sleep(270)
    #Replaced time.sleep(270) with audio loop starting here
    snoozeTime = (int(time.strftime("%H", time.localtime())) * 100) + (int(time.strftime("%M", time.localtime())))
    pg.mixer.music.set_volume(1.0)
    clock = pg.time.Clock()
    try:
        pg.mixer.music.load(dream_track)
        print("Music file %s loaded!" % dream_track)
    except pg.error:
        print("File %s not found! (%s)" % (dream_track, pg.get_error()))
        return
    pg.mixer.music.play()
    while pg.mixer.music.get_busy():
        elapsedTime = (int(time.strftime("%H", time.localtime())) * 100) + (int(time.strftime("%M", time.localtime())))
        if abs(snoozeTime - elapsedTime) > 0:
            pg.mixer.music.stop()
            break  
        clock.tick(30)
    time.sleep(1) #Added to see if the delay would change anything... it did not
    """for event in pg.event.get():
        if event.type == pg.KEYDOWN or event.type == pg.KEYUP:
            if event.key == pg.K_SPACE:

                return"""
    #And ending here
    if get_up():
        alarm(getup_file) #3. After snooze loop exits, alarm() is called again(no input)
        return
    elif snoozed > 1:
        pg.mixer.music.set_volume(0.75)
    else:
        pg.mixer.music.set_volume(0.5)
    alarm(alarm_file) #3. Same issue when called here, not that I'm surprised

def alarm(music_file):
    print("Starting Alarm Procedure")
    clock = pg.time.Clock()
    try:
        pg.mixer.music.load(music_file)
        print("Music file %s loaded!" % music_file)

                if event.key == pg.K_SPACE: #2. Space Bar is pressed and snooze() is called on initial loop
                    pg.mixer.music.stop()
                    snooze() #4. Called immediately when entering loop? Where is the input coming from??
                    return
                if event.key == pg.K_ESCAPE:
                    raise SystemExit
                if event.key == pg.K_RETURN:
                    pg.mixer.music.stop()
                    return
        # check if playback has finished
        clock.tick(30)
    alarm(music_file)

def InitMixer():
    # set up the mixer
    freq = 44100     # audio CD quality
    bitsize = -16    # unsigned 16 bit
    channels = 2     # 1 is mono, 2 is stereo
    buffer = 2048    # number of samples (experiment to get right sound)
    pg.mixer.init(freq, bitsize, channels, buffer)

def job():
    InitMixer()
    # optional volume 0 to 1.0
    pg.mixer.music.set_volume(0.5)
    alarm(alarm_file) #1. Initial call for alarm() started by schedule
    #snooze() #If I comment out the call to alarm() before this and uncomment this it works fine

schedule.every().friday.at('13:40').do(job)

while True:
    schedule.run_pending()
    for event in pg.event.get():
            if event.type == pg.KEYDOWN or event.type == pg.KEYUP:
                if event.key == pg.K_ESCAPE:
                    raise SystemExit
    time.sleep(1)
print("Oops!  End of Script reached.")

Until now this was working fine, I added the audio loop to snooze() and it started. Any help would be greatly appreciated because I'm lost at this point. As far as I can see there is no reason snooze() should be being called.

Edit:

For testing purposes I added:

for event in pg.event.get():
        if event.type == pg.KEYDOWN or event.type == pg.KEYUP:
            if event.key == pg.K_SPACE:
                print("I hit space again for you")
                return

to snooze() directly following time.sleep(1) and it shows it is definitely seeing the space bar. Why? Is event not on a frame by frame basis? Does it register keydown on the frame space is pressed and then keyup on a later frame?
