Detect faces with OpenCV

face_cascade = cv2.CascadeClassifier("path/to/opencv/sources/data/haarcascades/haarcascade_frontalface_alt.xml")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, 1.1, 3)

Play sound with PyGame

import pygame as pg

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)

pg.mixer.music.load(file_name)
pg.mixer.music.play()

Notes

Ways to load variables/parameters in Python

Solution1

import json
cfg = json.load(open('api_key.json'))

Solution2

with open('api_key.config','r') as f:
    for line in f:
        if line:          # skip blank line
            exec(line)

Solution3

import pickle
pickle.dump(Face, open('res/saved_face.txt', 'wb'))
Face = pickle.load(open('res/saved_face.txt', 'rb'))
