Please show us some more code -- especially the function containing and the
function calling the above chunk.
Generally speaking, a function terminates when execution reaches the first
return statement, e. g.
def f():
for i in 1, 2, 3:
return i
will always return 1. A generator, on the other hand,
def g():
for i in 1, 2, 3:
yield i
will yield 1, 2, and 3, but the calling code then needs itself a for loop:
for i in g():
# do something with i
My guess would be that you should either modify your for loop to
> attobject = context.get_attobject()
> navstring = context.get_uclattribute(attobject, 'ucl_navhide')
> hiddennavelements = navstring.split(' ')
for hiddennavelement in hiddennavelements:
# do something with hiddennavelement
or just return all elements at once
def some_func():
# ...
attobject = context.get_attobject()
navstring = context.get_uclattribute(attobject, 'ucl_navhide')
return navstring.split(' ')
and then operate on the items in the hiddennavelements list in the calling
code:
for element in some_func():
# do something with element
