What do you think is better about Python’s syntax? I generally like modern JavaScript’s syntax. I always figured the appealing part about python is the very good standard library.

List comprehension, the indent syntax that makes it very readable, the builtin functions, globally everything. The philosophy of python is well described here: https://www.python.org/dev/peps/pep-0020/ https://www.python.org/dev/peps/pep-0020/ I especially likes this one: > There should be one-- and preferably only one --obvious way to do it. It's true that the standard library is good, but generally I do more things with basic python than the base of other languages. And honestly I've never understood how js prototypes work. Python just feels better. The syntax is less cluttered. That's a huge point of python.

- sequence[-1] - sequence[start:finish:step] - no need for "===" - try/except with specific exceptions - context managers - yield from - "in" on any iterable - raise from - every empty object is false, all other are true - spread work on all iterables, not just arrays - f"{2:03}", f"{2:.2f}" and f"{date:%m/%d/%Y}" - / and // - no need for variable declaration keywords - 0b1111 - "else" in loops - := makes for explicit assignation + comparison instead of a footgun - None instead of null + undefined - set literals - matmul operator - foo > bar > baz - sorting callback semantics - dunder methods for operator overriding - list, dict and set comprehension - generator expressions - byte literals - raise SystemExit() for clean script exit - raw strings - automatic string literal concatenation - positional/keyword only parameters - can use *args and **kwargs together, as opposed to spread - docstrings - typing is part of the language, no need for a transpiled dialect like typescript - "async for" and "async with" That's only what I come up on the fly, I'm pretty sure I can double the list. Then of course, do we consider builtin to be part of the stdlib, since it doesn't require any import? Because there is a load to say there. JS does have some nice stuff too though: - ? and ?? - futures are more ergonomic than coroutines and awaitable anyway - more powerful destructuration - regex literals
