As we enter a new decade, we asked programming experts—including several of our own O’Reilly authors and instructors—for their thoughts on what’s in store for some established players and fast-growing languages.
The biggest news this year in Python is that creator and “benevolent dictator for life” Guido van Rossum retired, leaving Python in the hands of the Python Steering Council. So far, it’s been a painless shift in power, which as Eric Matthes, author of Python Crash Course, argues, should come as no surprise, since “Guido has carried himself, and his role in the community, with such poise for so long.” 2020 will also see the end of support for Python 2.7, which will likely cause its share of headaches among holdouts.
