You write Python programs using Python, not assembly.

Perhaps if you provide more info on what you want to do, someone can
suggest a different way...

Re: can i write a assemly language programs in python [In reply to]

I wonder if the OP is trying to find out whether python programmes can
be compiled and run as stand alone executables.

(I know assembly and machine code are not the same, but it might be
what they're after.)

On windows you can use http://www.py2exe.org/ to bundle python
programs into stand alone executables. They're not compiled, but your
code and all the modules it relies on are brought together, meaning
you can deliver a single exe than can be run like any other windows
program.

Maybe that helps...

Assembly language is a different programming language than Python. You
can use both in the same process, much in the same way you can use C or
C++ with Python. In fact, some of the system DLL's are written (partly)
in assembler, though mostly in C or C++.

You'll need to tell us what your real goal is. Are you a python
programmer trying to optimize some loop? Are you taking a course in
assembler, and hope that somehow Python will help? Do you have Python
installed on your system? What system is it?

As far as I know, Python has no "inline assembler" mode, as C does. So
anything written in assembler would be in a separate DLL, not mixed in
your .py files. It's not hard to mix assembly files with C or C++ files
(or Pascal, or dozens of other compiled languages), and link them into a
single DLL. But Python's access to that DLL will be done through a
module like ctypes, or SWIG.

It is possible that he meant how to write assembly *with* python.
Or how to translate python to assembly.

As it turns out, CPython translates Python to byte code and has a dis
(assembly) module that produces very nice assembly code ;-)
So that is one answer to his question.

Definitely.

Or maybe he meant if you can have both Python and assembler code in
the same source file, but I haven't heard of it. If what you are
trying to do is write a faster version of some part of your code, try
SWIG: http://www.swig.org/

Playing the guessing game is a time sink, and since nobody has done it
so far, I will: OP, please read

Examine CorePy http://www.corepy.org

"CorePy is a complete system for developing machine-level programs in
Python. CorePy lets developers build and execute assembly-level
programs interactively from the Python command prompt, embed them
directly in Python applications, or export them to standard assembly
languages."

I have never used CorePy yet, but it's an awesome project ^_^
With some care and work even Python programs can get fast enough :-)

If you mean dis.dis() that only gives you byte code. I assumed he was
referring to native code assembly.

I guess I'd better stop guessing <grin>.

Bah, writing assembly language is easy in Python:

print("MOV EAX, [EBX]")
print("XOR EBX, EBX")

Just adjust the strings for your favorite processor architecture
and Python will produce the assembly code you want.

Now compiling assembly to *machine* code...or calling between
Python and assembly...that's another matter. But writing
assembly language programs in Python? Easy. ;-)

"PyASM is a full-featured dynamic assembler written entirely in
Python. By dynamic, I mean that it can be used to generate and execute
machine code in python at runtime without requiring the generation of
object files and linkage. It essentially allow 'inline' assembly in
python modules on x86 platforms.

"PyASM can also generate object files (for windows) like a traditional
standalone assembler, although you're probably better off using one of
the many freely available assemblers if this is you primary goal."

No, dis is a disassembler and it gives readable assembly code, not the
raw numerical bytes. Its purpose is to make byte code + other parts of
the code object humanly readable.

As far as I know, there is no assembler that would turn the exact output
of dis back to its input.
