Creating function object from text

[Edward C. Jones]

Suppose I have a piece of text that defines a function:

text ="""\
def fun(i):
return i + 2
"""

How do I turn this into a function object, f, which can be called or
passed around?

exec text

If you need to do this other than in the global namespace of the
module, read up on the exec statement and how you can pass in a
dictionary of your own.

Aside from Peter's advice, I'd recommend you to look into timeit.py and
doctest.py.
These two library is a good example of how to use exec and compile in a
real application.

Bonjour !

Ce code fonctionne, chez moi :

src='''def toto(i):
return i*2'''

exec src
print toto(3) # => 6

Mais, dans certains cas, je suis obligé d'ajouter :
global toto

Bonne soirée !
