We dig into all things Python, which Allen thinks is pretty good, and it’s rise in popularity, while Michael and Joe go toe-to-toe over a gripe, ahem, feature.

Why Python?

A Brief History of Python. Very Brief.

• Python is a general-purpose high-level programming language, which can be used to develop desktop GUI applications, websites, and apps that run on sophisticated algorithms.
• Python was created in 1991, before JavaScript or Java, but didn’t make major leaps in popularity until 1998 – 2003, according to the Tiobe index.
  • Coincidentally, this lines up with the early days of Google, where they had a motto of “Python where we can, C++ where we must”.
• In 2009, MIT switched from Scheme to Python, and others in academia followed.

Some Python Benefits, But Only Some

• It’s an easy language for new developers as well as those who don’t consider themselves developers, such as data scientists or hobbyists, but have a need write some code.
• Python has a great standard library when compared to languages like JavaScript that largely rely on third party libraries to provide depth in functionality.
• It’s cross platform. As long as we’re talking OS.
  • Mobile? Not really, as that space is consumed with Swift, Java, and Objective-C. But with things like Pythonista, you can write and execute Python on mobile.
  • Web? No, at least not on the client side. That space is dominated by JavaScript. But with frameworks like Django and Flask, you can use Python on the server side.
• In addition to the standard library, there are also many great/popular third party libraries, like NumPy, that are available on PyPi.

The Downsides to Python

• Performance when compared to a natively compiled application because it’s a dynamic, interpreted language.
  • Which brings up the late binding type system.
• The lack of mobile and web presence as previously mentioned.
• Legacy issues when dealing with v2, which is still in use.
• Language features that haven’t aged well, such as PEP-8.
• Quirks like self, or __init__, private functionality, and immutability.
