Hi @Akshay Verma, it sounds like you are trying to iterate over a task (or possibly the result of calling a task, which is also a task). Hard to say without more code - can you provide an example?

08/19/2019, 1:11 PMi am doing the following:
Copy code
@task
def generate_context_level_data(mlsi, lvnr, tol):
ml, ci = td_split_clv(mlsi, lvnr, tol)
return ml, ci
td_input = {'a': 1, 'b': 2, 'c': 3}
with Flow('TD') as flow:
td_input = Parameter("td_input")
context_level_ml, context_level_ci = generate_context_level_data(td_input['a'],
td_input['b'],
td_input['c'])j

Ah ok, it’s because you are assigning the result of
generate_context_level_datacontext_level_mlcontext_level_cigenerate_context_level_dataTry this instead:
Copy code
context_result = generate_context_level_data(...)
context_level_ml = context_result[0]
context_level_ci = context_result[1]Python will let us index an unknown object like
context_result(Note, I can’t promise this will work exactly as written because it depends on what is actually coming out of
generate_context_level_dataa
