Answer 1

First you have to get a list of all the files which ends with '.mp3' in the directory (os.listdir, see os):

import os

path = "C:/Users/pc/Desktop/sample_songs/"
all_mp3 = [os.path.join(path, f) for f in os.listdir(path) if f.endswith('.mp3')]

then select a random file from the list (random.choice, see random):

import random

randomfile = random.choice(all_mp3)

Play the random file:

import pygame

pygame.mixer.init()
pygame.mixer.music.load(randomfile)
pygame.mixer.music.play()

Minimal example:

import os
import random
import pygame

directory = 'music'
play_list = [f for f in os.listdir(directory) if f.endswith('.mp3')]
print(play_list)
current_list = []

pygame.init()
window = pygame.display.set_mode((600, 100))
font = pygame.font.SysFont(None, 40)
clock = pygame.time.Clock()

window_center = window.get_rect().center
title_surf = None

run = True
while run:
    clock.tick(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    
    if not pygame.mixer.music.get_busy():
        if not current_list:
           current_list = play_list[:]
           random.shuffle(current_list)
        current_song = current_list.pop(0)
        pygame.mixer.music.load(os.path.join(directory, current_song))
        pygame.mixer.music.play()
        title_surf = font.render(current_song, True, (255, 255, 0))

    window.fill(0)
    if title_surf:
        window.blit(title_surf, title_surf.get_rect(center = window_center))
    pygame.display.flip()
    
pygame.quit()
exit()

You can use os.listdir() to get a list of all files in a folder. Then use random.choice() to choose a random file.

If all files in the directory are MP3 files, you could use something like this:

import os
import random

path = "C:/Users/pc/Desktop/sample_songs/"
file = os.path.join(path, random.choice(os.listdir(path)))
mixer.init()
mixer.music.load(file)
mixer.music.play()
