>So what's that mysterious reason that makes writing dynamically typed language faster?

Less ceremony.

But no ceremony is necessary in the cases where types can be inferred - and in the cases where types can't be inferred you probably do want to to be explicit about them even in a dynamic language.

It's not just the types, it's the whole APIs, culture etc.

Java, for example, is no picnic, whether it can now infer some types or not.

In Python I don't even need a main().

How is

    if __name__ == "__main__":
        main()

different from a main()?

It's only needed if you're importing the file as a library/module somewhere.

You don't even need that.

  print("hello world")

will run just fine

It's different in that it's optional in Python.

I agree Java is a high-ceremony language, but not all statically typed languages are like that.
