Hi all, I am trying to get the following to work, but cant seem to do
it the way i want to.
ok, so I come into python and do the following:
>>x = 1
then, i have a file called test.py in which i say:
print x
Now, after having defined x =1 in the python interpreter, i come in and
say:
import test
it has a problem, which i can understand, because it is in its own
namespace,
but even if i say:
from test import *
the interpreter still gives me the error:
NameError: name 'x' is not defined
the only way i can get it to work is if i say: execfile('./test.py')
how can i get this to work by importing and not execfile?
thanks for your help! 1 1272

Dennis gave you one way: import __main__ into test.
Another way to come close is to put the print inside a function.
test.py
---------
def p(): print x
Then your script could say
import test
test.x = 1
test.p()
If you don't already, you need to know that import only executes the code
for a module the *first* time you import it. So normally, top level code
in modules consists of function and class definitions and perhaps the
initialization of a few module-level constants or variables.

PHP puts most of its functions into a big flat global namespace.
That leads to short function names - but creates a namespace
minefield for programmers.
Lots of the functions are legacies from the days before PHP
got object-oriented features.

I'm trying to build a completely plug-in based system. One of my
problems is importing a package dynamically. I'm trying to emulate the
import command. The __import__() function or imp module doesn't help me
much because they only return the module. I want to register the module
with it's name in the current namespace. I can do it by:
globals() = __import__(module_name)
But I don't think it's a good thing to access the global namespace...

Having changed a VB.Net(2003) DLL project, I'm getting Type
Loading problems in other code that uses my DLL. In my source
code, I have a Namespace Statement something like this:
Namespace XYZ.AProject
but when I build the DLL project and open the resulting DLL up
in ILDASM, the Namespace has been *translated* to
"XYZ.Aproject".

Since many of the modern computer languages have built-in namespace
features, I can't understand why not add this feature into standard C.
I've heard many people complain of the lacking of namespace in C. Of
course, namespace doesn't eliminate name polution, but it helps more
than just to put some prefix before a function name. Is it because
adding namespace will make C more complex or some other reasons?

Is it best to include the code "using namespace std;" in the source or
should each keyword in the std namespace be qualified by the namespace tag,
such as
std::cout << "using std namespace" << std::endl;
Myself I am not sure which I prefer, it is certainly easier to specify that
the std namespace is being used instead of tagging each member of the
namespace?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
