Özellik Değeri

T5

Geçerli Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> nesnenin beşinci bileşeninin değeri.

Örnekler

Aşağıdaki örnek, Detroit şehri, Michigan için 1860-2000 arasındaki nüfus verilerini içeren 17 kayıt düzenli bir nesne oluşturur. 17 tanımlama grubunun beşinci bileşeni 1880'deki popülasyondur. Örnek, popülasyon değerini görüntülemek ve 1880 ile 1890 arasındaki yıllık nüfus değişikliği oranını hesaplamak için özelliğini kullanır Item5 .
