TypeError: unsupported operand type(s) for %: 'NoneType' and 'tuple'
args = ("unsupported operand type(s) for %: 'NoneType' and
'tuple'",)
But according to the same error, level = 0 [the NoneType, I presume]
and name = 'prodCat1', which is most certainly not a tuple! Why the error?
TIA,

Come on Victor,
Given the error, you can easily see that
tree.append("%s%s") % ("\t" * level, name)
is involved in the error you get.
The correct thing may be
tree.append("%s%s" % ("\t" * level, name))
It should be easy for you to spot.
FYI, tree.append('%s%s') returns None, then ("\t" * level, name) is the
tuple applied to None through the % operator. That is why you get the
above error.
Cheers,
JM
