    As a python developer and user of websites, please no. The web is already a slow mess and my laptop is already spinning up fans on some websites that really shouldn’t do anything much more complicated than load text and images from a database and display them. CPython would make it exponentially worse. At least pick a sensible performance focused implementation.

    Yes. Please. Although something strongly typed would be even better. It’s ridiculous the world runs on a language built in 2 weeks.

      Python is actually mostly strongly typed. Strongly (e.g. can’t use a number as a string without explicitly converting it), but dynamically (can change type of variable at runtime). You probably would prefer a statically typed language and I agree.

        Alright, thanks for the help with terminology. I’m a bit confused about changing types at runtime. I thought a compiled or interpreted language stopped having types at runtime, because at that point it’s all in assembly. (In this case of course it’s scripting, which someone pointed out to me elsewhere)

          That’s a compiled language, an interpreted language is translated to assembly at runtime, in pythons case: pretty much one line at a time.

          Disclaimer: To the best of my knowledge, please correct me where I’m wrong.

            That’s really only native compiled languages. Many popular languages, such as C#, Java, etc. Lie somewhere in between. They get compiled to intermediary byte code and only go native as the very final step when running. They run in a runtime environment that handles that final step to execute the code natively. For .NET languages that’s the CLR (Common Language Runtime).

            For .Net the process goes like this:

            • You write the code
            • Code is compiled to MSIL
            • At runtime when the MSIL is executing a JIT (just-in-time) compiler translates the MSIL into native code.
            • The native code is executed.

            Java has a similar process that runs on the JVM. This includes many, many languages that run on the JVM.

            JavaScript in the browser goes through a similar process these days without the intermediary byte code. Correction, JS in modern browsers also follow this process almost exactly. a JIT compiler compiles to bytecode which is then executed by the browser’s JS engine. Historically JS has been entirely interpreted but that’s no longer the case. Pure interpreted languages are pretty few and far between. Most we think of as interpreted are actually compiled, but transparently as far as the dev is concerned.

            Last, but certainly not least, Python is also a compiled language, it’s just usually transparent to the developer. When you execute a python program, the python compiler also produces an intermediary bytecode that is then executed by the python runtime.

            All that being said, I welcome any corrections or clarifications to what I’ve written.

            I did know the difference, but I didn’t realise it ran one line at a time! I had kind of assumed it at least did one pass through everything before giving output. Thanks.

              I believe it does “one pass” when it loads the code into ram, because syntax errors can be caught before anything runs. But I think the actual interpretation happens pretty much one line at a time :)
