Development of python
In the first stage, CNRI (National Research and Innovation Association founded by Robert Kahn1986) was an important unit supporting the early development of python, and most of the achievements before python 1.5 were completed during this period.
In the second stage, during the BeOpen period, GuidoVenRossum cooperated with BeOpen Company. During this period, Python2.0 was released, even python 1.6 was released at the same time, but it has been maintained separately in principle.
In the third stage, DC period, Guido has left BeOpen Company and brought the development team to DigitalCreations(DC) Company, which is famous for developing Zope system, so this cooperation has attracted much attention.
