100 functions/second
installed to global namespace doesn't sound well.
What on earth are you doing needing to use exec to create hundreds of
functions??
:-)
Have you considered not using exec at all, and using a good old-fashioned
factory function and closures?
def factory(x):
def i

UnboundLocalError: local variable 'bar' referenced before assignment
This works, though (at least it does on 2.7):
--> exec "def foo():\n\tglobal bar\n\tbar+=1\n\treturn 1\n"
--> bar = 9
--> foo()
1
--> bar
10
Laszlo, why do you think you can't use exec?
I'm sorry, first I was not aware of

A quick test in Python 2.4.5:
exec "def foo():\n\tbar+=1\n\treturn 1\n"
bar=2

You can't use:
exec "blah blah" in globals()
?
I've not used exec, nor its Python 3 equivalent exe
Hi,
I have a program that generates source code for a function. I need to
compile that function so that it can be executed (relatively) fast
later. In most cases, I'll be generating about 10 functions per second,
and evaluate them frequently. But sometimes I'll have to generate 100
functio
