Normally people put Python in the scripting category. I learnt typed languages like C++ and Java at first. People who learn languages like these tend to put Python in a non-serious category. The post was more ironic than litteral.
After 5 years of following the mailing lists i realised that there is more than the eyes meet. My hobby has always been language engineering / compiler theory and just recently i realised that Python is pretty serious about language features. I have been following language feature proposals from various languages. Some decide to avoid Python's route, but others have been trying hard to catch up with Python. One gleaming example is the switch case. JS recently proposed pattern matching, referencing Python and explaining why the proposal is a cool treatment of the usecase. As a side note, if by scripting we mean OS commands, then Python started as a sysadmin language. -- https://mail.python.org/mailman/listinfo/python-list
