Console-defined objects can be pickled as well. ">>>edit()" opens
console.log. Editor objects are pickled between statements.
Python 2.5.1 furtherconsoles-display.py logging to My Documents
\console.log
>>> class A:
... b=0
...
>>> from pickle import loads,dumps
>>> loads(dumps(A))
<class workmodule.A at 0x00B28030>
>>> loads(dumps(A)).b
0
>>> edit()
Loaded ok
and the few lines from console.log:
#Mon May 07 2007 07:55:30 PM Python win32 2.5.1 in furtherconsoles-
display.py
class A:
b=0
from pickle import loads,dumps
loads(dumps(A))
#fb: <class workmodule.A at 0x00B28030>
loads(dumps(A)).b
#fb: 0
edit()
Hard coded paths on lines 24 and 67. Hope that's copy-and-pasteable
