py2app add multiple libraries to setup.py

Question

I used tkinter, pytube and os libraries in my project. I found a setup.py example but I don't how to add my libraries to setup file. Can anybody help me? This is the example file:

from setuptools import setup
APP = ['pomodoro.py']
DATA_FILES = []
OPTIONS = {
'argv_emulation': True,
'iconfile': 'icon.icns',
'plist': {
'CFBundleShortVersionString': '0.2.0',
'LSUIElement': True,
},
'packages': ['rumps'],
}
setup(
app=APP,
name='Pomodoro',
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'], install_requires=['rumps']
)
