Okay, I've run into another problem. I've saved the code to a string,
so I can call it up when I need it. I want to keep these functions all
together, though, so I'm pushing them into a dictionary when I execute
it. It seems like when I put it in a dictionary, though, it messes up
the scope of the functions contained within. For example:
import cPickle
def Main():
holder =}
functiontest =def PickleTest():\n\tprint cPickle"
exec functiontest in holder
print holder["PickleTest"]()
Main()
... produces:
Traceback (most recent call last):
File "pickletest.py", line 11, in <module>
Main()
File "pickletest.py", line 9, in Main
print holder["PickleTest"]()
File "<string>", line 2, in PickleTest
NameError: global name 'cPickle' is not defined
Is there any way to do this so that the functions have access to the
higher scope?
Thanks.
Why not use import ? Simply recreate the source file, if necessary, and
import it again.
If you must import without it being in a clear text file, check out the
deprecated imputil module, standard in 2.x, but removed in Python 3.0.
And if you find some way to get __import__ or one of its relatives to
work from a stream instead of a file, please let us know.
