SpotiPy - Control Spotify using AppleScript and Python

This is part of my research using AppleScript and Python.

import cmd
import os
import subprocess
from time import sleep

Activate = """osascript -e 'tell application "Spotify" to activate'"""
Start = """osascript -e 'tell application "Spotify" to play'"""
Exit = """osascript -e 'tell application "Spotify" to quit'"""
Next = """osascript -e 'tell application "Spotify" to next track'"""
Previous = """osascript -e 'tell application "Spotify" to previous track'"""
Pause = """osascript -e 'tell application "Spotify" to playpause'"""
Play = """osascript -e 'tell application "Spotify" to playpause'"""
Artist = """osascript -e 'tell application "Spotify" to artist of current track as string'"""
Album = """osascript -e 'tell application "Spotify" to album of current track as string'"""
Track = """osascript -e 'tell application "Spotify" to name of current track as string'"""

class SpotiPy(cmd.Cmd,object):
    intro = 'Welcome to SpotifyCli for MacOS! Type help or ? to list commands.\n'
    prompt = 'SpotiPy> '

def do_start(self, s):
    subprocess.call(Activate, shell=True)
    sleep(1)
    subprocess.call(Play, shell=True)
def help_start(self):
    print "Enter start to activate Spotify Player"

def do_exit(self, s):
    subprocess.call(Exit, shell=True)
def help_exit(self):
    print "Enter exit to close Spotify"

def do_pause(self, s):
    subprocess.call(Pause, shell=True)
def help_pause(self):
    print "Enter pause to pause Spotify player"

def do_play(self, s):
    subprocess.call(Play, shell=True)
def help_play(self):
    print "Enter play to pause Spotify player"

def do_next(self, s):
    subprocess.call(Next, shell=True)
    sleep(3)
    print "Track :"
    subprocess.call(Track, shell=True)
    print "Artist :"
    subprocess.call(Artist, shell=True)
    print "Album :"
    subprocess.call(Album, shell=True)
def help_next(self):
    print "Enter next to play next track"

def do_previous(self, s):
    subprocess.call(Previous, shell=True)
    sleep(3)
    print "Track :"
    subprocess.call(Track, shell=True)
    print "Artist :"
    subprocess.call(Artist, shell=True)
    print "Album :"
    subprocess.call(Album, shell=True)
def help_previous(self):
    print "Enter previous to play previous track"

def do_status(self, s):
    print "Track :"
    subprocess.call(Track, shell=True)
    print "Artist :"
    subprocess.call(Artist, shell=True)
    print "Album :"
    subprocess.call(Album, shell=True)
def help_status(self):
    print "execute shell commands"

def do_clear(self, s):
    subprocess.call("clear", shell=True)
def help_clear(self):
    print "Clear screen"

def do_quit(self, line):
    return True

def help_quit(self):
    print "Bye...."

if __name__ == '__main__':
    SpotiPy().cmdloop()
