Learn How to Create an MP3 Music Player in Python

Everybody loves listening music wouldn’t it be cool to have our very own mp3 music player. So, in this python project, we are going to create an mp3 player with the help of python and its libraries. Let’s start the python mp3 player project.

Python MP3 Music Player

We will create an mp3 music player in which we can play the song, pause it, resume it, and navigate from the current song to the next song as well as previous songs.

We will be using Python and its libraries. The first library that we will be using is Tkinter which is a widely used GUI library offered by python, we do not have to install it separately, as it comes with python itself.

Next, we will be using the mixer module of a very famous python library called Pygame.

Pygame is basically used to create video games, it includes computer graphics and sound libraries. Mixer is one such sound library. Then, we will use the os library of python to interact with the Operating system.

Face Recognition with Python and OpenCV

What is face recognition? Or what is recognition? When you look at an apple fruit, your mind immediately tells you that this is an apple fruit. This process, your mind telling you that this is an apple fruit is recognition in simple words. So what is face recognition then? I am sure you have guessed it right. When you look at your friend walking down the street or a picture of him, you recognize that he is your friend Paulo. Interestingly when you look at your friend or a picture of him you look at his face first before looking at anything else. Ever wondered why you do that? This is so that you can recognize him by looking at his face. Well, this is you doing face recognition.

But the real question is how does face recognition works? It is quite simple and intuitive. Take a real-life example, when you meet someone first time in your life you don’t recognize him, right? While he talks or shakes hands with you, you look at his face, eyes, nose, mouth, color, and overall look. This is your mind learning or training for the face recognition of that person by gathering face data. Then he tells you that his name is Paulo. At this point, your mind knows that the face data it just learned belongs to Paulo. Now your mind is trained and ready to do face recognition on Paulo’s face. Next time when you will see Paulo or his face in a picture you will immediately recognize him. This is how to face recognition work. The more you will meet Paulo, the more data your mind will collect about Paulo and especially his face, and the better you will become at recognizing him.

Now the next question is how to code face recognition with OpenCV, after all this is the only reason why you are reading this article, right? OK then. You might say that our mind can do these things easily but to actually code them into a computer is difficult? Don’t worry, it is not. Thanks to OpenCV, coding face recognition is as easier as it feels. The coding steps for face recognition are the same as we discussed in the real-life example above.

• Training Data Gathering: Gather face data (face images in this case) of the persons you want to recognize
• Training of Recognizer: Feed that face data (and respective names of each face) to the face recognizer so that it can learn.
• Recognition: Feed new faces of the persons and see if the face recognizer you just trained recognizes them.

OpenCV comes equipped with a built-in face recognizer, all you have to do is feed it the face data. It’s that simple and this how it will look once we are done coding it.
