Hmm..
Hi guys. I am new to python, i never done any program in python ( as I was a programmer in .Net) , however I need to recompile python source codes as we are migrating form python 1.5 to 2.4.

I found this error --> SyntaxError: unqualified exec is not allowed in function '_sourceRules' it contains a nested function with free variables

ape ke benda nyer nih ??
Tak paham eden..


please .. senior2... tolong bagi tunjuk ajar kat budak baru/hingusan nih


Thanks .........

lagi senang kalau ko post relevant source code kat sini..

anyway, a quick google shows that it has something to do with lambda functions in python, which unfortunately i'm not that familiar

berikan kod awak then orang bleh tunjuk aper yg tak betul.. tapi generally message tu tunjukkan ader yg tak kena dengan kod yang awak "exec" tu.. try something like "exec <expr> in globals()", di mana <expr> tu aper2 la yg awak nak exec.

Error nya ialah :



File "DCAMgr.py", line 140, in ?
import DCARulesEngine
File "/home/r32813/genesis/Product/DCAMgr/DCARulesEngine.py", line 166
exec('attr=' + module + '.__dict__')
SyntaxError: unqualified exec is not allowed in function '_sourceRules' it contains a nested function with free variables

-- This is the file :

exec('attr=' + module + '.__dict__')
methods = filter( lambda f, a=attr : type(a[f])==types.FunctionType and f[0] != '_' , attr.keys() )
for k in methods:
if k not in self.pythonProcsDict['stdlib'].keys():
if k not in self.pythonProcsDict['customlib'].keys():
self.pythonProcsDict['customlib'][k] = module

apa yg awak perlu buat adalah qualify penggunaan exec, i.e dengan "exec 'attr=' + module + '.__dict__' in .." (tengok exec statement nyer reference) atau gantikan nested function yang ader free variable (ni termasuklah anonymous function yang awak define guna lambda). free variable means variable yg awak refer dalam suatu code block, tapi ia tak ditakrifkan dalam code block tersebut.
