New submission from Jervis Whitley jervi...@gmail.com:
complex() raises ValueError when parsing a string argument containing both real
and imaginary where one of the real or imaginary is a decimal.
To reproduce:
complex(1.1 + 2.1j)
ValueError: complex() arg is a malformed string

once on the pygame list.

I agree that it's an alternative. There are a number of alternatives.
However the OP was asking for a neater/easier alternative. I argue
that introducing an external module/function to do the exact same thing
as a built-in type's method doesn't exactly qualify as a neater/easier
alternative.
What I was wondering
was whether a similar construct was considered for a while loop or even an
if clause, because then the above could be written like this:
if open(filename, 'rb') as f:
while f.read(1000) as buf:
# do something with 'buf'
see here, and the associated bug

Hi,
I like this idea.
I've put together a short patch that will implement inline
assignment.
if f() - name:
use(name)
or more powerfully:
if f() - name == 'spam':
usespam(name)
the old syntax if something as x: is still available
Jervis Whitley jervi...@gmail.com added the comment:
If we allow this, how many of the following will be allowed?
if expr as name: block
while expr as name: block
expr as name # alternative to name = expr
This patch implements your final point:
expr as name (albeit with a nominal
Jervis Whitley jervi...@gmail.com added the comment:
Regarding the proposed syntax:
if (f() == 'spam') - name:
newname = name.replace('p', 'h')
Surely that should assign the *bool* result of comparing f()
with 'spam' to name? Doing anything else is opening the door to a
world

Hi all,
This patch takes the approach of assuming utf-8 format encoding

This moves the for-loop out of slow Python into fast C and should be much,
much faster for very large input.
_Should_ be faster.
Here is my test on an XP system Python 2.5.4. I had similar results on
python 2.7 trunk.
WORD = 'g' * 100
WORD2 = 'g' * 50 + 'U'
BIGWORD = 'g' * 1 + 'U'
