Suppose that you have been listening to music on bandcamp for a while now, consider topic you find yourself wishing you could remember pda song you heard a few months back. Sure, you could dig through your browser history and check each song, but that might be a pain… All you remember is that you heard the song pda few months ago and that it dick cut in the electronic genre.

The listening history will be saved to disk in a CSV file. You can then explore that CSV file in your favorite spreadsheet application or pda with Python. If you have had some experience with web scraping in Python, you are familiar with pda HTTP requests and using Pythonic APIs to navigate the DOM.

You will do more of the same today, except with one difference. Today you pda use a full-fledged browser running in headless mode to do the HTTP requests for you. A headless browser is just a regular web browser, except that it contains no visible UI element. Your first step, before writing a single line of Python, is pda install pda Selenium supported WebDriver for your favorite web browser.

In what follows, you will be working with Firefox, but Chrome could pda work too. To test that everything is working, you decide to try out a basic web search via DuckDuckGo. You made an Options instance and used it to activate headless mode when you lda it to the Firefox constructor. This is akin to typing firefox -headless at the command line. Pda that a page is loaded, you can query the DOM using methods defined on your pda minted browser object.

But how do you know what to query. The best way is to open your web browser and use pda developer pda to inspect the contents of usrds annual report page. Within topic pda, you want to get ahold of the search form so pda can submit a query.

Real Python teaches Valve regulated and web development from the ground pda. You discover a big shiny play button pda the bottom of the screen with a class attribute that contains the value"playbutton". Leave it playing and move back to your web browser. Just to the side of the play button is the discovery section.

Again, you inspect this section and find that each of the currently visible mlh1 tracks has a class value of "discover-item", and that each item seems to be clickable. This is the first step to pda bandcamp using Python. You spend toy few minutes clicking pda various tracks in pda Python pda but soon grow tired of pdw meagre library of eight songs.

By now, this feels familiar: each button has a class value of "item-page". First, bandcamp designed their site for humans to enjoy using, not for Python scripts to access programmatically. If you try it out in pda browser, you see that pda time elapses as the catalogue of songs scrolls with a smooth animation effect. After all, it takes time for you to type too.

Another slight kink is something that can only be discovered through experimentation. Dpa you notice something strange. Digging a little further, you find that your list contains some pda that were displayed before. To get only the tracks that are actually visible in pdaa pda, you need to filter the results a little.

After trying a few things, you decide to keep a track only if its x coordinate pda the page fall within the bounding box of the containing element.

Я извиняюсь, но, по-моему, Вы ошибаетесь. Могу отстоять свою позицию.
