Psyco is no longer supported

Well I redid my little experiment with my [color=#FF0000]48 python solutions[/color] and got this now:

Python 2.5 + psyco: [color=#FF0000]48 AC + 0 TLE[/color]
Python 2.6: [color=#FF0000]19 AC + 28 TLE[/color]
Python 2.6 + pysco: [color=#FF0000]28 AC + 20 TLE[/color]

This shows to me that in general python 2.6 has worse performance. Psyco helps a little bit, but the overall performance is still a problem. We are going to suffer (even more) to make python solutions ACceptable.

You can check the list of executions here: br.spoj.pl/status/diegocaminha/signedlist/1

• I wonder if the designers of python language care at all about performance

Sure. The numbers I gave are just for having some general idea of the impact in the version update. Some of the solutions can get AC by optimizing the algorithm (when I see an easy time constraint problem, I usually prefer a clean/easy/'fast enough' solution), but my personal impression is still many (extra) problems would not get acceptable. But it is just my (non-expert) point of view.

Just some facts:

CLTZ:
2.5 .... 2.62
2.6.1 .... 2.97
2.6.2 .... 3.92

STAMPS:
2.5 .... 0.64
2.6.1 .... 1.14
2.6.2 .... 1.54

I dont think the Python developers have made their homework. They should do some exercises on SPOJ instead. Soon we get TLE on TEST.
Can we resume to 2.5?

SBANK: spoj.pl/status/SBANK,zzz/

It was AC with 5.62s, now the same my code got TLE

What algorithm? In my code only a dozen of lines. Nothing to improve.

PS
I vote for switching back to Python 2.5

If the time limit is 7 s and there are python solutions AC in < 5 s and your solution gives TLE: There IS something to improve!

I have in store my ACcepted C++ code

PS
Adding Sevens: spoj.pl/ranks/ANARC08B/lang=PYTH
All of this summer submissions (i.e. v.2.5). Today my py code gets only TLEs (I've never solved this prob before).

What can be improved in my TLE code?

import psyco
psyco.full()
def foo():
    a = (\
        '063',
        '010',
        '093',
        '079',
        '106',
        '103',
        '119',
        '011',
        '127',
        '107')
    b = {\
    '063':'0',
    '010':'1',
    '093':'2',
    '079':'3',
    '106':'4',
    '103':'5',
    '119':'6',
    '011':'7',
    '127':'8',
    '107':'9'}

import sys
w = sys.stdin.readlines()

for wi in w:
    s = wi.strip()
    if s == 'BYE':
        return
    p = s[:s.index('+')]
    q = s[s.index('+') + 1:][:-1]
    pp = ''
    for i in range(0, len(p), 3):
        pp += b[p[i:i + 3]]
    qq = ''
    for i in range(0, len(q), 3):
        qq += b[q[i:i + 3]]
    z = str(int(pp) + int(qq))
    r = ''
    for zi in z:
        r += a[int(zi)]
    print s + r
foo()

alas... my dial-up connection is too slow for downloading anything with size more than 1-2MB

Forum jest po to aby odpowiadać na pytania? Niestety, "ale nie mam innego pomysłu" to nie pytanie , mimo to jeszcze raz "powiem":
Jest algoliga.pl1 a tam z lewego boku, taki mały, podobny do tego tu na spoju, niebieski napis [color=#4000BF][b]forum[/b][/color]. "Idąc" tam warto wcześniej odblokować w swojej przeglądarce wykonywanie skryptów.

PS
W zasadzie wystarczyłoby tylko zwrócić uwagę na pierwszy link w moim podpisie.

No pochwal się...

Jak napiszesz to przeczytam. Mogę nawet wrzucić to zadanie do mojego folderu "SPOJ TODO" żeby było jednym z następnych które rozwiąże (może nawet zanim zaczniesz pisać )
