Summary: Nested Scopes bug (Confirmed)
Initial Comment:
Bug confirmed.
description:
names that a in a scope just above the scome of the
nested block (function) do not appear that functions
globals thus bracking SOME (!) of the code that uses
them. in particular the eval function, and all code
that explicitly searces the name in the globals.
code:
//see the attached file.
output:
- a NameError raised in function nested_1:
'NameError: global name 'a' is not defined'
- a NameError raised in function nested_2:
'NameError: name 'a' is not defined'
workarround:
explicitly pass the variable to the function as its
default argument (as in nested_0).
NOTE: declaring the name global does not work (as
shown in function nested_1).
//see the attached file for more details.
test results:
there appears to be a gap between the globals and the
locals of a nested function.
test systems:
WIN2K v.5.00.2195 SP2
- ActivePython 2.2 Alpha 2 build 1 (ActiveState)
Python 2.2a2+ (#22, Sep 5 2001, 14:10:41) [MSC 32 bit
(Intel)] on win32
- Python 2.2 (#1, Dec 31 2001, 15:21:18) [GCC 2.95.3-5
(cygwin special)] on cygwin
FreeBSD 4.5 (LocalBuild)
Python2.2 //I do not remember the exact build.
With Respect..
Alex.
