Here is what i am trying to do:
if len(targets) == 0:
avg = frozenset([tuple(.123/(nodes_num - 1))])
for t in range(nodes_num):
if t == node:
continue
node_p = (avg,t)
node_weig.append(node_p)
I don't know what i am doing wrong but all it says avg = fro... float object is not iterable
This is your problem: tuple(.123/(nodes_num - 1))
The tuple constructor takes an iterable and makes a tuple from the values it produces. Obviously, .123/(nodes_num - 1) is a float, which can't be iterated. If you want to make a one element tuple of this value, use: (.123/(nodes_num - 1),) (note: That trailing comma is necessary to make a one element tuple, otherwise the parens are just grouping the operation, not wrapping it in a tuple).
So the resulting line would be:
avg = frozenset([(.123/(nodes_num - 1),)])
That will make a len 1 frozenset containing a len 1 tuple with the calculated float value. If the goal is just a frozenset of that one value, you don't need the tuple wrapping at all, and can simplify to:
avg = frozenset([.123/(nodes_num - 1)])
Now, whether either does anything meaningful for your scenario I don't know, but it's the source of your error.
From the doc:
Return a tuple whose items are the same and in the same order as iterable‘s items. iterable may be a sequence, a container that supports iteration, or an iterator object. If iterable is already a tuple, it is returned unchanged.
.123/(nodes_num - 1) is a float,that's why you got the error:
TypeError: 'float' object is not iterable
If I don't misunderstand your meaning,you can try to use
tuple([.123 / (nodes_num - 1)]) to make it iterable.
