The example with list comprehension was nice, I always wondered if this was possible without calling the same function twice, I will use it for sure

I saw the walrus operator in the wild a few weeks ago and I couldn't find a decent explanation of its purpose in Python. I was pretty pumped when I saw this video pop up in my feed.

@xzex2609 Жыл бұрын
in the first example if you did not use () between the walrus and the non equality operator then the lower priority of the walrus operator would cause a problem. you can not use command := input() != 'q' ; unless (command := input) != 'q'

Is this potentially something that a compiler could "figure out" at run time, and "optimize" what actually gets run toward the more efficient method of doing it? Idk the formal words to use, I just know I've seen comparisons between python and C, and shown that certain things written in python that might look "not optimal" is actually interpreted by the compiler at run time and "figured out" and "made" more efficient by using the "actual" best method that should/could have been used

Another interesting use case might be if you do list comprehension in combination with slow rest requests for example.

There are many more good uses for the walrus operator. Some of the uses can be found in James Powell's vids...

As for the last example, doesn’t Python interpreter optimise it automatically? As far as i know in C if you call function with the same argument for a few times its result is kept in memory. This optimisation is made by compiler
@obed8182 жыл бұрын
You are actually right, even though i dont get why when i try simple code it id about always faster with walrus, but i think C only store hashable value although im not 100% sure

Guido von Rossum quit his gig as THE Python guy over the walrus operator. Not so much the operator itself as much as the bitter fighting that erupted over it's inclusion. Part of the argument was that if == vs = could cause problems, imagine what kind of trouble you could get in with accidental assignments when you really just wanted a boolean result. There were many in the community that felt non explicit assignments were as evil as the reviled 'Goto'. Sorry I had to use language like that here, but sometimes just have to man up and know there were in the past forms of code worse than Stalin, Mao, and Hitler combined. Funny thing is, the same peeps that loved goto hated recursion. Having a subroutine call itself was considered extremely naughty back in the day.
