[$] Unpacking for Python comprehensions

Date:
Fri, 21 Nov 2025 16:09:50 +0000

Description:
Unpacking Python iterables of various sorts, such as dictionaries or lists,
is useful in a number of contexts, including for function arguments, but
there has long been a call for extending that capability to comprehensions . 
PEP798 ("Unpacking in
Comprehensions") was first proposed in June 2025 to fill that gap.  In early
November, the steering council accepted the PEP, which means that the feature 
will be coming to Python3.15 in
October2026.  It may be something of a niche feature, but it is an
inconsistency 
that has been apparent for a whileto the point that some Python programmers
assume that it is already present in the language.
