It’s kinda different although you can do some similar things. IMO the ruby one is more powerful because it effectively allows you to customize language syntax by supplying a block. And it fits nicely with the stdlib and libraries (ex map yields to a block to do the mapping). Ruby also has an enumerator that does some similar things to pythons yield: https://docs.ruby-lang.org/en/master/Enumerator.html https://docs.ruby-lang.org/en/master/Enumerator.html Pythons yield is more commonly used for iteration and stuff although it does allow some neat tricks for scoping things.
