hehe, só vendo o ['Arquivo de configuracao da arquitetura'] da pra ver que é
brasileiro =)
I didn't undestand, what didn't worked?
I've tryied this, and all went ok:
>>> list1 = ['name', 'value']
>>> list2 = ['path', 'c:\some\path']
>>> list3 = [list1, list2]
>>>
>>> print str(list3).replace('\\\\','\\')
[['name', 'value'], ['path', 'c:\some\path']]
