[portland] dis.dis in IronPython / latest PPUG meetup

[kirby urner]

Thanks to all for a fine evening last night.  My blogged write-up
linked below.**

I was sounding pretty confidant that I knew what dis.dis would do on
IronPython:  spit out IL byte codes right?

I just tested that hypothesis.  But first, the CPython version:

IDLE 2.6.6
>>> def f(x):  return 2*pow(x,3) + 5*pow(x,2) + 1

>>> import dis
>>> dis.dis(f)
  1           0 LOAD_CONST               1 (2)
              3 LOAD_GLOBAL              0 (pow)
              6 LOAD_FAST                0 (x)
              9 LOAD_CONST               2 (3)
             12 CALL_FUNCTION            2
             15 BINARY_MULTIPLY
             16 LOAD_CONST               3 (5)
             19 LOAD_GLOBAL              0 (pow)
             22 LOAD_FAST                0 (x)
             25 LOAD_CONST               1 (2)
             28 CALL_FUNCTION            2
             31 BINARY_MULTIPLY
             32 BINARY_ADD
             33 LOAD_CONST               4 (1)
             36 BINARY_ADD
             37 RETURN_VALUE
>>>

And now for something completely different....

IronPython 2.6.1 (2.6.10920.0) on .NET 4.0.30319.1
Type "help", "copyright", "credits" or "license" for more information.
>>> 6+6
12
>>> import dis
>>> def f(x):  return 2*pow(x,3) + 5*pow(x,2) + 1
...
>>> dis.dis(f)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files (x86)\IronPython 2.6 for .NET

NotImplementedError

I should do some reading obviously.  It looks like it almost worked,
but looks can be deceiving.

See ya'll on chat maybe,

Kirby

PS:  next PPUG I could do a lightning talk on what I'm up to with PSF a
little.  Here's some documentation.

It's partly that Pycon / Havana I'm thinking about, also Pycon / Tehran.
Anyone going to Python / Ukraine?  Not me.  Vilnius was great
though (a EuroPython, not a Pycon).

Or I could do 5 mins on Martian Math, which I shared through
Reed College this summer.

(lotsa Python + VPython)
