Re: Uniform Function Call Syntax (UFCS)
So, just to summarise the discussion: There was some very mild support for readable pipelines, either using UFCS or an alternative syntax, but the Pythonic way to make combinations of function and method applications readable is to assign to variables over multiple lines. Make the code read down, not across. The idea that a class method could override a function using UFCS didn't get much traction. From Zen of Python, explicit is better than implicit means no differences in behaviour, depending on context. The fact that x.y and x.__getattr__ may behave differently under UFCS is also a problem. Since hasattr testing and AttributeError catching are both commonly used now, this could cause real problems, so could probably not be changed until Python 4. Finally, Gilbert Sullivan are definitely due a revival. -- https://mail.python.org/mailman/listinfo/python-list

If you don't mind the numpy dependency I can't see any disadvantages.
You might also have a look at pandas:

Is this sort of a constraint implementable in Python?
Hello Everyone,
I'm working on a python code to input matrices into CPLEX solver. I have most
of my code running fine but as of now, I don't know how to express this
constraint. My objective is to minimize the number of nodes. I have got one of
the weirdest looking constraints which I don't know how to express in Python
because python basically takes matrices and inputs them into cplex. My
constraint is as below. This was what I wrote in AMPL
minimize phy_nodes: sum {w in PHY_NODES} x_ns[w] ;
s.t. Phy_nodes_Eq{w in PHY_NODES, dns in DEMAND}:
x_ns[w] = 1 == x_SGW[dns, w] + x_PGW[dns, w] + x_MME[dns, w] + x_IMS[dns, w] +
x_PoP[dns, w] = 1
else x_SGW[dns, w] + x_PGW[dns, w] + x_MME[dns, w] + x_IMS[dns, w] + x_PoP[dns,
w] = 0;
Could you help me fix this problem?
Thank You

That would require knowledge about what the used algorithms are, why they are implemented as they are, that would require extensive testing with test cases that don't exist.

Your error reports always seem to resolve around benchmarks despite speed
not being one of Pythons prime objectives
Computers store data using bytes
ASCII Characters can be used storing a single byte
Unicode code-points cannot be stored in a single byte
therefore Unicode will always be inherently slower than ASCII
implementation details mean that some Unicode characters may be handled
more efficiently than others, why is this wrong?
why should all Unicode operations be equally slow?

the weirdest looking constraints which I don't know how to express in Python

constraint is as below. This was what I wrote in AMPL
minimize phy_nodes: sum {w in PHY_NODES} x_ns[w] ;
s.t. Phy_nodes_Eq{w in PHY_NODES, dns in DEMAND}:
x_ns[w] = 1 == x_SGW[dns, w] + x_PGW[dns, w] + x_MME[dns, w] + x_IMS[dns, w] +

Could you help me fix this problem?
Thank You
This is more a CPLEX question than a Python question. (Or rather a
question about some Python/Cplex interface.) Do you have access to any
kind of a CPLEX forum or a Cplex-via-Python forum? I think that's much
more likely to get you an answer.

[issue21326] asyncio: request clearer error message when event loop closed
STINNER Victor added the comment: This issue was discussed on the python-dev mailing list. The conclusion is that adding a new method to asyncio is safe because asyncio has a provisional API (whereas the selectors module doesn't). Ok, Python 3.4.2 will have the new method BaseEventLoop.is_closed(), that's all. -- versions: +Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21326 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21679] Prevent extraneous fstat during open()

[issue20504] cgi.FieldStorage, multipart, missing Content-Length
Matthias Urlichs added the comment:
Actually, the problem is cgi.py around line 550:
clen = -1
if 'content-length' in self.headers:
try:
clen = int(self.headers['content-length'])
except ValueError:
pass
if maxlen and clen maxlen:
raise ValueError('Maximum content length exceeded')
self.length = clen
if self.limit is None and clen:
self.limit = clen
… so self.limit ends up being -1 instead of None. :-/
Somebody please change this test to
if self.limit is None and clen = 0:
