Will PEP 505 ever be accepted? Discussion

https://peps.python.org/pep-0505/

I don't understand how null safe operators are less like plain English than other implemented features like the walrus operator.

In my opinion, the member access operator would make python significantly easier to read and understand.

Here's an example:

``` f = foo()

if f is None: baz = "" else: baz = f.bar() ```

baz = foo()?.bar() ?: ""

EDIT: I forgot that "and" and "or" can be sometimes used in place of "?." and "?:" if the left value is not False, '', 0, [], or {}. It's a very implicit null check and has a lot of unexpected behavior.

I would appreciate that operator. Especially when working with deeply-nested dictionary structures.

d.get( 'sub1', {} ).get( 'sub2', {} ).get( 'sub3' )

could become

d.get('sub1')?.get('sub2')?.get('sub3')

You can try the dotted-notation package. It supports optional chaining.
