Suppose Which you've been listening to music on bandcamp for a little while today, and you end up wishing you could remember a tune you heard a few weeks ago.

Sure, You can dig through your browser and assess each tune, but that might be a pain... All you remember is that you heard the song a couple of months back and that it had been from the electronic genre.
 selenium online training,


"Wouldn't It be great," you think to yourself,"when I had a list of my listening history? I could only look up the electronic songs from two months before, and I'd definitely find it."

Today, you will build a fundamental Python

The Listening history is going to be saved to disk in a CSV file. After that you can research that CSV file on your favourite spreadsheet application or perhaps with Python.

If You've had some experience with internet scraping in Python, you're familiar with making HTTP requests and using Pythonic APIs to navigate the DOM. You will do more of the same now, except with one gap.

Now you'll use a full-fledged browser Running in headless way to perform the HTTP requests for you.

A headless Browser is only a regular web browser, but that it includes no visible UI element. Just like you would expect, it may do more than make requests: it can also render HTML (although you cannot see it), keep session info, and also perform social network communications by running JavaScript code.

If You wish to automate the modern net, headless browsers are crucial.

Setup
Your First step, before writing a single line of Python, is to install a Selenium supported WebDriver to your favourite browser. In what follows, you will be working with Firefox, but Chrome can easily get the job done too.

Assuming That the route ~/.local/bin is in your implementation PATH, here is how you'd put in the Firefox WebDriver, known as geckodriver, onto a Linux device:

Next, you install the selenium package, Using pip or anything you like. If you created an electronic environment for this project, you just type:

Now it is time to get a test drive.

The DOM using techniques defined on your freshly minted browser object. However, how do you know what to question?
The best way is to open your web browser And utilize its developer tools to inspect the contents of the page. At the moment, you want to get ahold of the research form so that you may submit a question. That's just what you wanted:

Groovin' on Tunes
You've tested that you can push a Headless browser using Python. You Can now put it to use:

1. You want to play audio.

2. You would like to browse and explore songs.

3. You would like information about what music is playing.

To start, you browse to Https://bandcamp.com and begin to poke around in your browser developer tools. You discover a big shiny play button to the bottom of the screen with a course attribute which contains the value"playbutton". You check it functions:

You should hear songs! Leave it playing and move back to Your web browser. Just to the side of this play button is the discovery section.
