Earlier today, I asked a question about the way Python handles certain kinds of loops. One of the answers contained disassembled versions of my examples.

I'd like to know more. How can I disassemble my own Python code?

Look at the dis module:

def myfunc(alist): return len(alist) >>> dis.dis(myfunc) 2 0 LOAD_GLOBAL 0 (len) 3 LOAD_FAST 0 (alist) 6 CALL_FUNCTION 1 9 RETURN_VALUE

Besides using dis as module, you can also run it as command line tool

For example, on windows you can run:

c:\Python25\Lib\dis.py test.py

And it will output the disassembed result to console.

Another way to use it: "python -m dis test.py"

Use the dis module from the Python standard library (import dis e.g. in an interactive interpreter, then dis.dis any function you care about!-).
