With APIs, you’ll be able to keep away from parsing HTML and as a substitute entry the info instantly utilizing formats like JSON and XML.

However, not all of the job listings seem to be developer jobs that you’d be excited about as a Python developer. So instead of printing out the entire jobs from the page, you’ll first filter them for some keywords. Run the above code snippet and you’ll see the text content material displayed. Since you’re now working with Python strings, you’ll be able to .strip() the superfluous whitespace. Author Bio
