Function Serialization

[Mike Tammerman]

Michele, thank you for the suggestion, it works as you mention.

But in my case the function is inside a string and I should exec the
string to get the function. Something like this

>>> fields = {}
>>> s = 'def f(): pass'
>>> exec s in fields
>>> f = fields['f']
>>> f
<function f at 0xb7a00bfc>
>>> import shelve
>>> d = shelve.open('test.db')
>>> d['f'] = f
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.4/shelve.py", line 129, in __setitem__
    p.dump(value)
TypeError: expected string or Unicode object, NoneType found

I am not a pro python developer, so I couldn't understand why it throws
exception. I am a bit confused.

Sincerely,

Mike
