For content management systems we use Plone which is based on Python. In addition, we use various Python frameworks, always choosing a matching framework for the project. Flask is used for simple applications, while Django or Pyramid are used for more complex applications. Tornado is used for high-performance applications.
Python has been developed by Dutch computer programmer Guido van Rossum. At that time, he worked at the Dutch research institute for mathematics and computer science (CWI). Afterwards, he worked at Google and currently he is working at Dropbox.
