The walrus operator := appeared only in 2018 with PEP 572. For more than 25 years, Guido van Rossum refused to have an expression assignment operator in Python (as there is in C for example). For old pythonistas like me, this operator breaks somewhat the clean syntax of Python because it allows assignments to be buried into complex expression instead of being clearly visible in the statements sequence. We used to accept the lack of this as a sacrifice for a greater cause.

I find that fascinating.

A lot of the consequences of the design choices in C is the ability to obfuscate your code. I'm sure the motivation was pure at the time as C was developed at the tail end of the punch card era and most of the techniques can save you some very valuable space on a punch card. What has developed over the years though, is a type of coder who loves using these tools to make the code all but unreadable while patting themselves on the back for saving a few keystrokes. My favorite example is: i += i++ + ++i; Having worked as a teacher, where clean and understandable is primary and also as an assembler coder and saw that the result of such lines actually results in more commands for the computer to crunch through; I have never been a big fan of these design choices.

Then I stumbled across Python. Python seems to be the language where all of the design choices were made to save on typing and to obfuscate the code. It is absolutely fascinating that in a language that seems to embrace ease of coding so highly above readability that one of the lead designers would shy away from something as comparably innocuous as an expression assignment operator.

Crazy.
