[python] generator seznamu - TypeError: object cannot be interpreted as an index

[Lukas Lisa]

Dobry den,
rad bych pouzil generator seznamu, bohuzel me prave
v situaci kde jej potrebuju nefunguje a me neni jasne
proc

podle jednoho prispevku v comp.lang.pyhon by generator
mel fungovat.
cituji:
It must have __hash__ and __cmp__ or __eq__ methods. Newstyle classes
inherit these from object.

cemuz promenna sluzby odpovida
In [31]: dir(sluzby)
Out[31]:
['__add__',
  ......
  '__eq__',
  ......
  '__hash__',
.....


nevite, v cem je zakopany pes?
diky za vysvetleni teto zahady :)
