[ANN] pypiserver 1.1.0 - minimal private pypi server
Hi, I've just uploaded pypiserver 1.1.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just 'pip install pypiserver'). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 1.1.0 - implement multi-root support (one can now specify multiple package roots) - normalize pkgnames, handle underscore like minus - sort files by their version, not alphabetically - upgrade embedded bottle to 0.11.6 - upgrade waitress to 0.8.2 in the standalone script - merge vsajip's support for verify, doc_upload and remove_pkg -- Cheers Ralf -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
A new webpage promoting Compiler technology for CPython
Hey all, With Numba and Blaze we have been doing a lot of work on what essentially is compiler technology and realizing more and more that we are treading on ground that has been plowed before with many other projects. So, we wanted to create a web-site and perhaps even a mailing list or forum where people could coordinate and communicate about compiler projects, compiler tools, and ways to share efforts and ideas. The website is: http://compilers.pydata.org/ This page is specifically for Compiler projects that either integrate with or work directly with the CPython run-time which is why PyPy is not presently listed. The PyPy project is a great project but we just felt that we wanted to explicitly create a collection of links to compilation projects that are accessible from CPython which are likely less well known. But that is just where we started from. The website is intended to be a community website constructed from a github repository. So, we welcome pull requests from anyone who would like to see the website updated to reflect their related project.Jon Riehl (Mython, PyFront, ROFL, and many other interesting projects) and Stephen Diehl (Blaze) and I will be moderating the pull requests to begin with. But, we welcome others with similar interests to participate in that effort of moderation. The github repository is here: https://github.com/pydata/compilers-webpage This is intended to be a community website for information spreading, and so we welcome any and all contributions. Thank you, Travis Oliphant -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

However, in this were the case then unittest would identify it as a problem, and I could relatively easily get a traceback and see from where it's originating. However, the unittests are passing fine (except for the pesky messages), so it's something else. I'm starting to think that what's happening is something like this: I have a cascade of generator objects (some hold on to others), and the unittests check both the exhaustion case and the non-exhaustion case (both cases are valid use cases). *Later on*, after the tests finish, the garbage collector starts tearing down the generator cascade, but in a different order. Some generators, while closing down, are attempting to close down other generators that no longer exist. So, notwithstanding your correct answer - I'm still stumped about finding out how to get rid of these annoying messages. Posting a minimal example that exposes the behaviour and reflects the situation in your actual code would definitely a good idea ;) But short of closing your generators in a controlled manner the only thing that might help is avoiding global names in the finally clause. Globals are all set to None when the module object is destroyed. Code that runs in that phase may fail for that reason: $ cat tmp.py class X: def __init__(self, name): self.name = name x = X(whatever) def g(): try: yield 42 finally: print x.name y = g() next(y) $ python tmp.py Exception AttributeError: 'NoneType' object has no attribute 'name' in generator object g at 0x7f3dbf3580f0 ignored $ cat tmp2.py class X: def __init__(self, name): self.name = name x = X(whatever) def g(x=x): try: yield 42 finally: print x.name y = g() next(y) $ python tmp2.py whatever I'd still recommend fixing the cause rather than the symptoms... -- http://mail.python.org/mailman/listinfo/python-list

asyncore.loop()

BSD socket communication framework does not itself support connection
indications
on connection-oriented protocols, so asyncore fakes the indication by
detecting
if socket is writable. As the writable was false = no write event = no
connection indication.
asyncore usage and documentation is bad, so when using the module, read the

code to understand it's usage and functioning, or use other implementation eg.

multiple 2.7.3 versions?
A colleague reports that this python from a recent Ubuntu x86_x64 Python 2.7.3 (default, Sep 26 2012, 21:51:14) contains a fix of this bug http://bugs.python.org/issue15212 however, all of my other Python 2.7.3s seem to lack this 'fix'. I would have thought that for a fix to appear in python we should at least get a micro version change, but the text here http://docs.python.org/2/faq/general.html#how-stable-is-python The developers issue “bugfix” releases of older versions, so the stability of existing releases gradually improves. Bugfix releases, indicated by a third component of the version number (e.g. 2.5.3, 2.6.2), are managed for stability; only fixes for known problems are included in a bugfix release, and it’s guaranteed that interfaces will remain the same throughout a series of bugfix releases. would seem to indicate that changes to the spelling of a public variable would not change even with a change to the micro level so my colleague's machine should not produce this output from compiler import consts dir(consts) ['CO_FUTURE_ABSIMPORT', 'CO_FUTURE_DIVISION', 'CO_FUTURE_PRINT_FUNCTION', 'CO_FUTURE_WITH_STATEMENT', 'CO_GENERATOR', 'CO_GENERATOR_ALLOWED', 'CO_NESTED', 'CO_NEWLOCALS', 'CO_OPTIMIZED', 'CO_VARARGS', 'CO_VARKEYWORDS', 'OP_APPLY', 'OP_ASSIGN', 'OP_DELETE', 'SC_CELL', 'SC_FREE', 'SC_GLOBAL_EXPLICIT', 'SC_GLOBAL_IMPLICIT', 'SC_LOCAL', 'SC_UNKNOWN', '__builtins__', '__doc__', '__file__', '__name__', '__package__'] where the originally mis-spelled SC_GLOBAL_EXPLICT has changed to SC_GLOBAL_EXPLICIT. Can someone explain how this 'fix' is leaking out onto his machine?

You call chr(piece) many times in this program. It would be better to
just have piece be a string rather than always converting it to one
every time you want to do something. Also comparing it with a numeric
code is fairly cryptic. I guess that ascii 32 is a space character but
I'd have to look that up to be sure.
def display_board(board):
print ' a b c d e f g h'
print '+---+---+---+---+---+---+---+---+'
for row in range(8):
for col in range(8):
Why not make board a list of lists. Then you can do:
for row in board:
for piece in row:
rather than using range().
Or perhaps you could have a dict that maps position tuples to pieces,
e.g.: {(1, 2): 'k', ...}
sys.stdout.write('| ')
sys.stdout.write(chr(board[row * 8 + col]))
sys.stdout.write(' ')
sys.stdout.write('|')
print 8 - row
print '+---+---+---+---+---+---+---+---+'
You seem to be using sys.stdout.write as a way of printing without a
trailing newline. In Python 2 you can get this effect by using:
print 'foo',
(note the trailing comma). In Python 3 you would do
print('foo', end=' ')
You can use the Python 3 syntax in your Python 2 script if you do
from __future__ import print_function so that your script works on
Python 2 and 3.
Also I would probably separate the function that generates the text
representing the board from the code that actually sends that
information to stdout.
def piece_moves(board, index, dx, dy, capture_flag, distance):
piece = board[index]
type = piece_type(piece)
cx = index % 8
cy = index / 8
You can use divmod for this:
cx, cy = divmod(index, 8)
Also in Python 3 index / 8 will return a float. Use // for floor
division in both versions (from __future__ import division).
for step in range(distance):
nx = cx + (dx * (step + 1))
ny = cy + (dy * (step + 1))
Why not make a function that yields these values and loop over that?
def continued_moves(x, y, dx, dy):
while 0 = x 8 and 0 = y 8:
x += dx
y += dy
yield x, y
if nx in range(8) and ny in range(8):
Use chained comparisons 0 = x 8 rather than testing for membership
in a range object. x in range(N, M) creates (in Python 2) a list
integers and then (in 2 or 3) iterates over that list to find an
object equal to x. This is inefficient and not as clear.
newindex = ny * 8 + nx
newpiece = board[newindex]
With a list of lists you could access the board with board[ny][nx]
which is clearer. Or with the dict: board[(nx, ny)].
The code below is overly indented. consider factoring it into functions.
newtype = piece_type(newpiece)
if capture_flag == MUST_CAPTURE:
if newtype != EMPTY and newtype != type:
board[index] = ' '
if (ny == 0 or ny == 7) and chr(piece) in 'Pp':
for promote in 'QRBN' if type == BLACK else 'qrbn':
board[newindex] = promote
yield board
else:
board[newindex] = piece
yield board
board[index], board[newindex] = piece, newpiece
elif capture_flag == MAY_CAPTURE:
if newtype == EMPTY or newtype != type:
board[index], board[newindex] = ' ', piece
yield board
board[index], board[newindex] = piece, newpiece
Rather than modifying and unmodifying the board in place (which is
fragile), could you not just have the compute_score function compute
the score as if the move had taken place? Then you could just yield
the move and the score.
break
elif newtype == EMPTY:
board[index] = ' '
if (ny == 0 or ny == 7) and chr(piece) in 'Pp':

In this case the innermost loop of the program is over the pieces on

in score as a result of each move).

inheritance and how to use it
Hi,
I use a module downloaded from the net. Now I want to build my own
class, based on the class SerialInstrument offered in this module -
and in my class I would like to initialize a few things, using e. g.
the method clear() offered by SerialInstrument. Hence I type:
class myClass(SerialInstrument)
self.clear(self)
def f1(self, str1, str2)
...do something etc.
I then get the message "self not know" from the statement
self.clear(self). I have tried many other notations - none worked.
What works is however the following code - specifying myClass
without the self.clear(self) in it:
x = myClass("argument")
x.clear()
How can I integrate this call into the definition of myClass? Thanks
for advice.
Bob

Bob Good job cutting down the sample. Naturally, it'd have been smart to tell us you don't get the same traceback this way. But it looks like the first problem is in that missing __init__() method. Instead of saying it doe not work it'd be good to examine just what error traceback you got when you did have it there. I suspect it's because you're passing parameters in when you invoke it (iodev, baud_rate = 57600) but you don't have any arguments. You don't even have the self argument. You are also missing the super call, as outlined earlier in this thread. So the base class won't being properly initialized once you fix the first problem.

Your question would make more sense if you would show your program and

played itself.

This is my code:

I would like it to show the computer guessing the numbers.
Hello. I think you code is Python 2.7. My solution uses Python 3 but I can
help you convert it if the solution is what you are looking for. My approach
as to create a class that tries to guess the right number. This code also
eliminates raw_input. I didn't know how important having it respond via
raw_input is to you. Code follows:
import random
import sys
class Guesser():
def __init__(self):
self.low = 1
self.high = 100
def getRand(self,x,y):
num = random.randint(x,y)
return num
def guess(self,guess,boundary):
if boundary == :
self.low = guess
elif boundary == :
self.high = guess
else:
self.low = 1
self.high = 100
return self.getRand(self.low,self.high)
def playagain(self):
choice = ['Y','N']
return random.choice(choice)
run = 0
while run == 0:
guess=1
guesses=0
guessestaken = 0
comp = Guesser()
num = comp.getRand(1,100)
result =
print (I am thinking of a number between 1 and 100)
while guesses == 0:
guessestaken += 1
try:
guess = comp.guess(guess,result) # replaces input
except:
print(Unexpected error:, sys.exc_info()[0])
raise
print(Your guess:, guess)
if guess == num:
print('Correct! It took you', guessestaken, 'guesses!')
guesses = 1
elif guess num:
print(My number is lower)
result =
else:
print(My number is higher)
result =
print(Do you want to play again?)
playagain = comp.playagain()# replaces input
print(playagain)
if playagain == N:
run = 1
Please let me know if you have questions or would like to discuss this solution
further.

python math problem
I am trying to calculate the coordinates at the end of a line. The length and angle of the line are given and I am using the following formula: x = (math.sin(math.radians(angle)) * length) y = (math.cos(math.radians(angle)) * length) The following are sample answers in the format (x, y) to the given length/angle values of the line: 120/0 = (0.0, 25.0) 120/89 = (24.9961923789, 0.436310160932) 120/90 = (25.0, 1.53075794228e-15) 120/91 = (24.9961923789, -0.436310160932) Why am I getting a string number instead of the expected answer for 120/90 which should be (25.0, 0.0).

Hence I type: class myClass(SerialInstrument) self.clear(self) def f1(self, str1, str2) ...do something etc. I then get the message self not know from the statement self.clear(self). Which is absolutely correct. Besides, I would have expected some syntax errors. You try to execute the clear() method during the definition of the class, not during the instantiation. Instantiation happens in the __init__() method.

What works is however the following code - specifying myClass without the self.clear(self) in it: x = myClass(argument) x.clear() Here the clear() is called on the object which has been created, so after calling the __init__() above (which is, roughly, equivalent to calling it at the bottom of __init__()). Thomas Thomas, This does not work either. The error comes while python analyses the code - even prior to executing my program But what I want to achieve is that this clear() is executed when the class is instantiatedwhich I do with the code x = myClass(COM7) Of course, when scanning the class definition, the argument COM7 is not yet known.

Nicholas,
Could it be that you use a more recent version ( e. g. 3.3) of python? I
found that raw_input is indeed no longer recognized. Use input instead and
your code will work - at least it did so with python 3.3 on my iPad.

With just a single character, it sounds like you want something like
whole = 123456:789
parts = whole.split(':') # or .split(':', 1)
interesting = parts[0]

Change your print statement to look like this:

With just a single character, it sounds like you want something like

parts = whole.split(':') # or .split(':', 1)

Classical CompSci teachings when working with floating point numbers
is to NEVER compare for equality. Instead one should compare against

Don't compare floats for equality is reasonably good advice.
Adding never to that advice, especially when shouting as you do, moves it
into the category superstition.
Consider:
- Python floating point integers are exact for entire range of -2**53
to 2**53, or about -9 million million to +9 million million; if you
are working with floats that have integral values in this range,
testing for equality is perfectly fine.
- If you work exclusively with fractional powers of two, such as 1/2,
1/4, 1/8, 1/16, etc. floats are typically exact.
- Testing against an epsilon raises as many problems as it solves:
+ What epsilon should I pick? How do I know if my epsilon is too small,
and therefore I'm rejecting values that I should accept, or too large,
and so I'm accepting values I should reject?
+ If my epsilon is too small, calculating abs(x - y) = epsilon is
exactly equivalent to x == y, only slower.
+ Should I test for absolute error, or relative error?
+ If relative error, how do I deal with values around zero where
division is likely to introduce excessive rounding error?
+ Not to mention the risk of dividing by zero.
- And how do I deal with INFs?

Any help will be greatly appreciated. Thank you very much! I'm rather surprised somebody hasn't jumped in by now. I thought your reworded query was quite well done. One of the source files is pretty large, but it's not your code, so that perhaps cannot be helped. I'm not sure why you included the code from hier_block2_.py, as I cannot see any reference to it. I'm surprised at the comment in the first file that said the code was generated. if it was generated by your efforts, perhaps there was something wrong with that. I know nothing about this gnuradio thingie, and you didn't supply a website url. I was wondering if the module is even intended to be run standalone, but I suppose the if __name__ == __main__ thing is a clue that it's supposed to. I found the mixture of trace lines to confuse the stack trace immensely, since the exception doesn't occur in the last source line quoted. Somebody better than I had best jump in and help. The error message referenced class gr_hier_block2_sptr, but I don't see where this is defined. So I'm not sure how to tell whether it does or should have a set_callback method. If nobody else jumps in, I'd suggest finding a forum that supports gnuradio, and ask there. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list

Python trademark - A request for civility
Folks, It seems that people have been sending threats and abuse to the company claiming a trademark on the name Python. And somebody, somewhere, may have launched a DDOS attack on their website. The Python Software Foundation has asked the community for restraint and civility during this dispute. Abuse and threats just bring the Python community into disrepute. http://pyfound.blogspot.com/2013/02/asking-for-civility-during-our.html -- Steven -- http://mail.python.org/mailman/listinfo/python-list
