Yes, in ASM a simple 25 or 33Mhz 386 computer was able to emulate
the
Spectrum. At least, under MSDOS, like did Warajevo, Z80, x128 and
"Spectrum"
from Pedro Gimeno.

Surely, much better and faster :-)

Is there a Python version of C's language #define statements?
Example:
#define ReadMem( (x) )memory[ (x) ]
Instead of using a function, when you call to ReadMem(), the code is
INCLUDED, (no function is called, the "compiler" just substitues the

Hi.
I'm trying to port (just for fun), my old Sinclair Spectrum emulator,
ASpectrum, from C to Python + pygame.
Although the Sinclair Spectrum has a simple Z80 8 bit 3.5Mhz
microprocessor, and no aditional hardware (excluding the +2/+3 model's
AYsound chip), I'm not sure if my loved scripted

Hi.
Until now, all my python programs worked with text files. But now I'm
porting an small old C program I wrote lot of years ago to python and
I'm having problems with datatypes (I think).
some C code:
fp = fopen( file, "rb");
while !feof(fp)
{
value = fgetc(fp);

Hi...
I'm trying to guess how to access attributes of an existing object
given the attribute name in a string. I mean:
class Object:
self.x = 12
self.y = 20
self.name = "blah"
def ChangeAttribute( object, attribute, value ):
# Insert here the code for object.attribute = value
X
( Surely if this question has been asked for a zillion of times... )
( and sorry for my english! )
I'm impressed with python. I'm very happy with the language and I
find Python+Pygame a very powerful and productive way of writing 2D
games. I'm not, at this moment, worried about execution speed

I haven't measured it, but this should be the fast solution in all

Well ... you could use:

...print a[i]
...if a[i] == 3: del a[i]

Thanks all for the answers ... I'll use a tuple as you said :)
Anyway, is interesting to know how to sort 2 lists when you dont want
to use tuples, so thanks also to Peter :)

No, I'm talking about "simple" lists, without REFERENCES to another

Is there a way to check the REAL size in memory of a python object?
Something like

or

or something like that ...
Thanks.

Hi :)
First of all, I must apologize for my poor english :)
I'm starting with python and pygame and for testing (and learning)
purposes I wrote an small "Map Editor" for a small game project I'm
going to start next month.
The tilemap editor is working fine, but reading Guido's Van Rossum
