It can be useful for jupyter too where usually the last thing you want to do in a cell is both to assign a variable and show its value.,(reply>), Whoa, I never considered that. I think it's still more convenient to just write the variable again in the last line, because then it's easier to enable/disable it (without having to remove the parentheses). And easier to move the code around, when you are exploring commands to later package into a function pipeline. Maybe if someone wrote a plugin for vs code/jupyterlab to switch between = and (:=) with one shortcut.,(reply>), agree, the simplest example is we don't need to print pandas df after reading it in the first block of code :p,(reply>), But this is not C++ where you add every feature that can be useful.
