>> If you are used to call backs, promises, tick() calls or closures, it will be natural to reach for them a lot, and be disappointed at their state in the Python ecosystem. It's a real disappointment that Python has no answer for JavaScript fat arrow. The fat arrow is the one construct that completely changes the structure of all the programs I write - it makes things extremely terse and I use it in nearly every function/method in some way. I'm a big fan of Python's whitespace structure but it seems to be an obstacle to creating single line functions that are both powerful and get multiple things done, which sometimes makes a program easier to read and more understandable. Sure there's lambda functions but I find them clumsy and hard to work with compared to the beauty of the fat arrow.
