I need to put in the var property of the first object from the list
that is not None. Somth like:
foo = first_of([any, beny, riki,]).name
Dont want to ugly if-cascade:
foo = any.name if name is not None else beny.name if beny is not None \
else riki.name if riki is not None
assuming you meant "foo = any.name if ***any*** is not None else
beny.name..."
If you have a fixed/hard-coded list of elements, you could
something like:
foo = (any or beny or riki).name
If you have dynamic list of elements:
class NoElementFound(Exception): pass
def first(iterable):
for element in iterable:
if element: return element
raise NoElementFound
lst = [any, beny]
if condition: lst.append(riki)
print first(lst).name
This first() is about the functionality of the SQL Coalesce()
function.
Hope this helps,
-tim
