What tools or libraries are there for decompiling python and exploring bytecode?

Lets say I have: ``` >>> def test(a): >>> print a ``` Now, I want to explore see how test looks like in its compiled form. ``` >>> test.func_code.co_code '|\x00\x00GHd\x00\x00S' ``` I can get the disassembled form using the dis module: ``` >>> import dis >>> dis.dis(test) 2 0 LOAD_FAST 0 (a) 3 PRINT_ITEM 4 PRINT_NEWLINE 5 LOAD_CONST 0 (None) 8 RETURN_VALUE ``` Is there an opensource and maintained decompiler I could use to turn the bytecode back into readable python code? update: thanks for suggesting decompile, but it's outdated (python2.3) and no one maintains it anymore. Is there anything for python2.5 or later?
