Why learn Python Django?
Django, a popular & high level python web framework, is Flat out amazing. Below are few of the reasons.
Instagram, Facebook, Disqus, Pinterest, NASA, The Washington Post and other top companies use Python with Django. For web developers, this means that mastering Python and its popular advanced frameworks like Django should ensure you’re able to find work or even build your own product or service as a startup.
Python is an ideal option for bootstrappers and startups because of its quick deployment and—as mentioned earlier—lesser amount of required code next to Java, C, and PHP among others.
Python Django framework supports the use of human-readable website URLs, which isn’t only helpful from the actual user’s perspective, but also to search engines, which use the keywords in the URL when ranking sites.
Django prevents a number of common security mistakes better than say, PHP does.
Moreover, average salary of a Django professional is $117,000 / year in US alone as reported by Indeed.com
