[...] I find that (space between the parentheses of a function call statement) too unnatural as a place where to put an assignment. It is not even "guarded" by a keyword like "if" or "while" which can help as indicators that an assignment may occur. Also, I think it's way too easy to confuse it with a keyword argument:
>>> foo(x = 1) # keyword arg >>> foo(x := 1) # assignment + value passing [...]
But the PEP 8 spellings are
foo(x=1)and
f(x := 1).
The extra spacing makes it obvious that this isn't a regular named argument. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.python.org/pipermail/python-dev/attachments/20180708/b3f492e2/attachment.html>
