According to several websites, Python is one of the most popular coding languages of 2015.

The programming language is currently being used by a number of high-traffic websites including Google, Yahoo Groups, Yahoo Maps, Linux Weekly News, Shopzilla and Web Therapy. Likewise, Python also finds great use for creating gaming, financial, scientific and educational applications 

At work, we are planning to migrate our WPF application from .NET Framework 4.7 to .NET Core 3.0. The main reason for doing so is that it was always a big pain to organize the updates of the .NET Framework on our customer machines. So being able to bundle .NET Core with our application is a big plus for us. Then, for sure, we are looking for the performance improvements brought by .NET Core and finally the new capabilities brought by the fast pace of innovation of .NET Core.
