Indexing the walrus operator

If you look at the main index: https://docs.python.org/3.10/genindex-all.html

You can find most operators, but you can't find the walrus operator.
Try Ctrl+F and search for "walrus", ":=", "named expression",
"assignment expression", "assignment"→"expression". You can't find
them anywhere in the index.

Sure, you can find them at the main search page:
https://docs.python.org/3.10/search.html?q=walrus

Again, a minor issue, but still worth fixing.

And since I know the walrus operator is new, I wonder if any of the
newer sections of the documentation could also suffer from the same
issue.

Please see PR #97921.

I added:

• := (colon equals)
• assignment expression
• walrus operator
