it compiles i have no problems with the compilation. The issue is the result

makes it clear that the thing you are passing to int() is in fact

Try removing the '.0', or use int(float(...)).

CPU usage while reading a named pipe
Hey everyone, I've been working on parsing (tailing) a named pipe which is the syslog output of the traffic for a rather busy haproxy instance. It's a fair bit of traffic (upto 3k hits/s per server), but I am finding that simply tailing the file in python, without any processing, is taking up 15% of a CPU core. In contrast HAProxy takes 25% and syslogd takes 5% with the same load. `cat < /named.pipe` takes 0-2% Am I just doing things horribly wrong or is this normal? Here is my code: from collections import deque import io, sys WATCHED_PIPE = '/var/log/haproxy.pipe' if __name__ == '__main__': try: log_pool = deque([],1) fd = io.open(WATCHED_PIPE) for line in fd: log_pool.append(line) except KeyboardInterrupt: sys.exit() Deque appends are O(1) so that's not it. And I am using 2.6's io module because it's supposed to handle named pipes better. I have commented the deque appending line and it still takes about the same CPU. The system is running Ubuntu 9.04 with kernel 2.6.28 and ext4 (not sure the FS is relevant). Any help bringing down the CPU usage would be really appreciated, and if it can't be done I guess that's ok too, server has 6 cores not doing much. -- http://mail.python.org/mailman/listinfo/python-list

My tail call optimizing decorator
Please critique this tail call optimizing decorator I've written. I've tried to fix the pitfalls of other proposed decorators, and the result is this one that supports mutual recursion, does not use exceptions, stack inspection or any implementation-dependent hack, and is pretty short and fast - the fastest out of the ones I could find and try. In fact, in tail-recursive environments I tested the impact of using the decorator is difficult to even measure, as the extra time the decorator takes to run is probably saved by the better use of cache memory. The only caveat is that if used in a function that's not called in a tail-recursive fashion, bad things will happen. def tailcall(f): '''Decorator that implements tail call optimization. Supports cooperative tail call - even when only one of the functions is decorated, and all exceptions pass through it. You can tell the functions that have been tail optimized because they have "tco" before them in the stack frame. The only caveat is that if you attempt to decorate a function that isn't called in a tail recursive fashion from another decorated function, you'll get wrong results.''' tdata = [False] #[Optimizing?] DO_CALL = object() #Call marker def tco(*a, **aa): if tdata[0]: return DO_CALL, a, aa else: tdata[0] = True ret = f(*a, **aa) while type(ret) is tuple and ret and ret[0] is DO_CALL: ret = f(*ret[1], **ret[2]) tdata[0] = False return ret tco.__doc__ = f.__doc__ return tco -- http://mail.python.org/mailman/listinfo/python-list
finding an element in a string
Hi,
I was wondering if you could help me with this:
I want to make an if statement in which I would like to find a certain word in a sentence; here is what i have so far:
x = raw_input("how are you?")
if x == "fine":
print "Good."
But that, obviously, will only respond "good" when one writes "fine". I was looking for a way for the program to respond "good" to any sentence that would contain the word "fine" in it.
I'm sure it's something ridiculously easy, but I have no idea how to do it! :)

Yes, 'str' is unnecessary. I just forgot to remove it from the code.

Nice!
The following also works using split and list comprehension (as
suggested in a brazilian python forum):
---
L = []
file = ['5,1378,1,9', '2,1,4,5']
str=''
for item in file:
L.append([float(n) for n in item.split(',')])

Great! Now it looks better :-)

Actually I'm trying to convert a string to a list of float numbers:
str = '53,20,4,2' to L = [53.0, 20.0, 4.0, 2.0]
As some of you suggested, using while it works:
-
L = []
file = ['5,1378,1,9', '2,1,4,5']
str=''
for item in file:
j=0
while(j= len(item)): break
if(str != ''):
L.append(float(str))
str = ''
j=j+1
print L
-
But I'm not sure this is an elegant pythonic way of coding :-)
Thanks for all suggestions!

Basic question
I've been studying python for 2 weeks now and got stucked in the
following problem:
for j in range(10):
print j
if(True):
j=j+2
print 'interno',j
What happens is that "j=j+2" inside IF does not change the loop
counter ("j") as it would in C or Java, for example.
Am I missing something?

Current module reference
HiHow do I get a reference for the current module I'm in ?I have a package called services with a __init__.pythat need to use getattr() to fill out a hash whithmy package attributes. But to use getattr, I need a object that references my package (kind of this this reference in Java).How can I do it ? the only way I found to o this is to call get attr from anothermodule that imports the services package. But I suppose it's not the only wayThanks for your helpMiguel-- Miguel Galves - Engenheiro de ComputaçãoJá leu meus blogs hoje?

Re: Python or Ajax?

Adding attribute to objetcs
Hello,I`m starting to learn python, and I hava a very good background in Javaand C/C++ programming. I was reading Dive into python chapter aboutOO and I saw that in python we can do the following:class Person: passjoe = new Person()joe.name = "Joe"joe.age = 13It seems that it is possible to add attributes to any object instancein run time, as in _javascript_. It seems to me that it can be a source of errors. One that come in my mind is the follwing:class Person: name = "" joe = new Person() joe.nome = "Joe"The code above adds an attribute called nome, but the programmer may think it's name.What is the real interest of this feature ? Is there a way to block this kind of error ? Thanks,Miguel-- Miguel Galves - Engenheiro de ComputaçãoJá leu meus blogs hoje?

List operation: Removing an item
Hi,
I've been (self) studying Python for the past two months and I have had
no background in OOP whatsoever.
I was able to write an interactive program that randomly selects an item
from a list. From a Main Menu, the user has the option to add items to
an empty list, show the list, run the random selector, and of course
quit the program. The program also complains if a user tries to add an
item that is already in the list prompting the user to enter another item.
I am trying to create a function that removes an item as specified by
the user. Apparently, the list operation "del list[:]" deletes the
entire list. Below is the sample function.
Any ideas, suggestions, or tips on the list operation I should be using,
or a better way of writing this?
TIA
shopList = ['eggs', 'milk', 'bread', 'juice', 'fruit', 'deli']
def removeItem():
"Remove an item from the list"
print
for items in shopList:
print items
print
dlete = raw_input("Enter the item you want to remove: ")
print
for item in shopList:
if dlete in shopList:
del shopList[:] # <--What is the correct function to use?
print "%s has been removed" % dlete
print "The new list is now", shopList
else:
print "Item is not in the list"

Perl XML::Simple and Data::Dumper - exists in Python?
Hi there, I'm a Perl programmer trying to get into Python. I've been reading some documentation and I've choosed Python has being the "next step" to give. Can you point me out to Python solutions for: 1) Perl's Data::Dumper It dumps any perl variable to the stdout in a "readable" way. 2) Perl's XML::Simple It maps a XML file into a Perl data structure. Does Python have something like these two tools? I've been googling before posting this and didn't find anything.

For instance, Python calls it's associative array structure a dictionary, and a checking the documentation index for dictionary turns up a link to the syntax for declaring one as display/dictionary. Read through the tutorial. Then look through some "interesting" modules in the standard library to see how these things fit together. I guess I'll just do that.

Getting into Python, comming from Perl.
Hi, list. I'm into a psicological doubt that I would like to share with you (you'll know why later on this mail). I'm a programmer with 5 year of experience into Perl. I'm on that point where you resolve problems without thinking on HOW you'll do it with that language but only on the problem itself. Since Perl 6 started I've been following it. The conclusion I have is they're making a whole new language and I'll have to learn it. This being said and, since I've to learn a new language, I've started thinking in a new language. I've noticed Python is getting more and more developers and many projects are being made. I've tryed to use python some times but I get frustrated very quick. I get myself many times needing to figure out how to loop through a list, declare an associative array, checking how to pass named parameters to functions, and simple things like that.
