Message378752
Subscription of list and dict (only with '') and ??? is at least puzzling. Removal of a new feature after release is a bad idea. But this new feature, expansion of subscription, needs to documented in
https://docs.python.org/3/reference/expressions.html#subscriptions
as legal code.
The current first line
"A subscription selects an item of a sequence (string, tuple or list) or mapping (dictionary) object:"
is no longer always true. This suggested replacement is:
"Subscription of a sequence (string, tuple or list) or mapping (dictionary) object selects an item from the collection."
Then at the end, add something like
"Subscription of certain type objects creates a Generic Alias.
where 'Generic Alias links to where such are documented. |
