Facial Expression or Facial Emotion Detector can be used to know whether a person is sad, happy, angry and so on only through his/her face. This Repository can be used to carry out such a task.

This is the code for this video by Ritesh on YouTube.

Facial Expression or Facial Emotion Detector can be used to know whether a person is sad, happy, angry and so on only through his/her face. This Repository can be used to carry out such a task. It uses your WebCamera and then identifies your expression in Real Time. Yeah in real-time!

PLAN
This is a three step process. In the first, we load the XML file for detecting the presence of faces and then we retrain our network with our image on five diffrent categories. After that, we import the label_image.py program from the last video and set up everything in realtime.

컴퓨터를 종료하는 Python 스크립트

Python은 다양한 기능으로 인해 널리 사용되는 스크립팅 언어입니다. 이 기사에서는 컴퓨터를 종료하는 Python 스크립트를 작성합니다. Python 스크립트를 사용하여 컴퓨터/PC/노트북을 종료하려면 “ ” 코드가 있는 기능을
사용해야 합니다 

import os
  
shutdown = input("Do you wish to shutdown your computer ? (yes / no): ")
  
if shutdown == 'no':
    exit()
else:
    os.system("shutdown /s /t 1")
