Hi,
I want to create a method within a class that is able to accept either a class
or an instance.
class MyClass(object):
@magic_decorator
def method(param):
# param can be MyClass (cls) or an instance of MyClass (self)
so I can do something like:
instance = MyClass()
MyClass.

Dear all,
I want to monkey patch a method that has lots of code so I want to avoid
copying all the original method for changing just two lines. The thing is that
I don't know how to do this kind of monkey patching.
Consider the following code:
class OringinalClass(object):

Hi,
I've been trying very, very hard to load an RSA key using M2Crypto but without

I have to run the asyncio.loop on a separated thread because the main

definitive solution I'll be doing a
os.kill(os.getpid(), signal.SIGKILL) inside the finally block.

Hi,
I'm writting an application that saves historical state in a log file.
I want to be really efficient in terms of used bytes.
What I'm doing now is:
1) First use zlib.compress
2) And then remove all new lines using binascii.b2a_base64, so I have
a log entry per line.
but b2a_base64 is far fro

Hi all,
I want to provide an encapsulated static attribute called _registry
for several classes.
I try to use inheritance in order to make it DRY: all classes inherit
from a BaseClass that implements the _registry encapsulation. But with
inheritance it doesn't work how I want, because a single ins

Hi!
I need to create a pretty complex class at runtime. something like
this one:

class VirtualUserLimitForm(ModelForm):

initial=monitor1.default_limit)
memory_limit = forms.Char
