What is your favorite Python syntactic sugar?
The thing I love about python is it's elegance; and I thing that is partially due to its syntactic sugar. Between list comprehensions, destructuring, enumerators, generators with yield, and a bunch more, what is your favorite
You're viewing a single thread.
Generators probably. It's the one thing i genuinely miss about python when i work in rust.
You're right. Having just
yield sthin a function instead of defining the data structure is such a game changer.impl Iterator for YourType?That's not quite the same as a generator. Iterators require explicit returns to yield control, and this involves dropping the entire stack frame.
True generators allow one to yield, which pauses the function and allows it to be resumed. The most similar thing to this in Rust is an async block/fn, but there is ongoing effort to generalize this so you could create an iterator from a generator.
cool!
