Weird local variables behaviors

[Sebastjan Trepca]

Hey,

can someone please explain this behavior:

The code:

def test1(value=1):
def inner():
print value
inner()
def test2(value=2):
def inner():
value = value
inner()

test1()
test2()

[trepca@sauron ~/dev/tests]$ python locals.py
1
Traceback (most recent call last):
File "locals.py", line 13, in <module>
test2()
File "locals.py", line 10, in test2
inner()
File "locals.py", line 9, in inner
value = value
UnboundLocalError: local variable 'value' referenced before assignment

Why can't he find the variable in the second case?
Thanks, Sebastjan
