How to chmod a file to: o-rwx ? (to change only the others mode)
os.chmod(fname, )
I was reading this [1], but the truth is that anything as 'S_IRUSR'
doesn't help enought.

When I use the next command in my home system:
$ python setup.py develop
Pyrex compiles the '.pyx' file without any problem. But after of
uploading it to Pypi, and when is installed via 'easy_install' it
doesn't builds any more. (I had to upload the '.c' file compiled on my
system)

Is there any way of use HMAC with RIPEMD-160?
Since that to create a ripemd-160 hash there is to use:
h = hashlib.new('ripemd160')
it looks that isn't possible
For HMAC-SHA256 would be:
-
import hashlib
import hmac
hm = hmac.new('key', msg='message', digestmod=hashlib.sha256)

I usually use a class to access to global variables. So, which would
be the correct way to set them --since the following classes--:
class Foo:
var = 'lala'
class Bar:
def __init__(self):
self.var = 'lele'
Or is it the same?

I understand very well that a service is a software which is accessed
through a network.
And the description given on Wikipedia [1] is "A 'Web service' (also
Web Service) is defined by the W3C as "a software system designed to
support interoperable Machine to Machine interaction over a network."

Akathorn Greyhat sent me by email the next solution, which althought
isn't generic it works well:
-
You could make your own class for that, maybe something like
#
class MyCoolDictionary(dict):
def __init__(self, *args, **kargs):
dict.__init__(self, *args, **kargs
I've a constructor with several values that must be used by any
functions:
---
class foo:
def __init__(self, foo1, foo2, foon):
self.__check(foo1=foo1, foo2=foo2, foon=foon)
self.__check2(foo1=foo1, foo2=foo2, foon=foon)
def __check(self, foo1, foo2, foon):
...
I think that would be very interesting thay Python would have a module
for working on base 96 too. [1]
It could be converted to base 96 the digests from hashlib module, and
random bytes used on crypto (to create the salt, the IV, or a key).
