Hello, everybody!
Could someone help me with coding this thing?
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
def not_none(obj):
return obj is not None
def first_of(seq, predicate=not_none, default=None):
for obj in seq:
if predicate(obj):
return obj
else:
return default
