Python: How to pass arguments to the __code__ of a function?

Question

The following works:

def spam():
    print \"spam\"
exec(spam.__code__)

spam

But what if spam

Answer 1

Can you change the function to not take any arguments? The variables is then looked up from the locals/globals where you can supply into exec:

>>> def spam():
...   print "spam and", eggs
... 
>>> exec(spam.__code__, {'eggs':'pasta'})
spam and pasta

(Why not just send the whole function as a string? Pickle "def spam(eggs): print 'spam and', eggs", and exec the string (after verification) on the other side.)
