Hello,
when I execute the following code (python 2.5)
def f(x):
def g():
return x
return g
print f(1)
print f(2)
I get an output like
<function g at 0x00AFC1F0>
<function g at 0x00AFC1F0>
So according to print I get the same function object returned at both
calls.
That's surprising, I would expect to get two distinct function objects
because their func_closure attribute has to be different. And indeed,
if I do
print f(1) is f(2)
instead, it prints False. Even more confusing, if I do
g1 = f(1)
g2 = f(2)
print g1
print g2
I get something like
<function g at 0x00AFC1B0>
<function g at 0x00AFC1F0>
ie. two distinct function objects are printed.
What's happening here?
Some clever optimization reusing function objects in special cases or
what ...?
