As Greg pointed..
g = {}
exec open('t.py').read() in g, g
is what you want.
But you can write it also this way:
exec open('t.py').read() in {}
because if you specify only globals, the same
dictionary is also used for locals. (locals() is
used as a default only if you don't specify globals)

Indeed, using 'globals()' and 'locals()' works. However,
both report the same underlaying object, which is a bit

not the same object as 'globals()' ?)

hi there,
I have trouble running some python code with 'exec':
t.py contains:
class Foo: pass
class Bar:
f = Foo
From a python shell I do:
>>> f = ''.join(open('t.py').readlines())
>>> exec f in {}, {}
Traceback (most recent call last):
File "", line 1, in ?
File "", line 2, in ?
