Hello all,
I'm trying to extract the code object from a function, and exec it
without explicitly passing parameters.
The code object 'knows' it expects to receive paramaters. It's
'arg_count' attribute is readonly.
How can I set the arg_count to 0, or pass parameters to the code object
when I exec it ?
>>> def f(x):
... print x
...
>>> c = f.func_code
>>> type(c)
<type 'code'>
>>> exec c
Traceback (most recent call last):
File "<input>", line 1, in ?
TypeError: f() takes exactly 1 argument (0 given)
>>> c.co_argcount
1
>>> c.co_argcount = 0
Traceback (most recent call last):
File "<input>", line 1, in ?
TypeError: readonly attribute
