Fungsi python getattr() digunakan untuk mengakses nilai atribut suatu objek dan juga memberikan opsi untuk mengeksekusi nilai default jika kunci tidak tersedia Show

Metode konvensional memakan waktu lebih sedikit daripada getattr(), tetapi ketika nilai default harus digunakan jika ada atribut yang hilang, getattr() adalah pilihan yang baik Aplikasi. Ada banyak aplikasi getattr(), beberapa di antaranya telah disebutkan dalam kasus tidak adanya atribut objek, dalam pengembangan web di mana beberapa atribut bentuk bersifat opsional. Juga berguna dalam kasus pengumpulan fitur Pembelajaran Mesin jika beberapa fitur terkadang hilang dalam pengumpulan data Apa metode default Getattr dengan Python?Fungsi Python getattr() digunakan untuk mendapatkan nilai atribut objek dan jika tidak ada atribut objek yang ditemukan, nilai default dikembalikan. Basically, returning the default value is the main reason why you may need to use Python getattr() function.
Bagaimana cara mendapatkan Getattr dengan Python?Sintaksis. getattr(obj, kunci, def) Parameter Pengembalian. Nilai objek jika nilai tersedia, nilai default jika atribut tidak ada. dan mengembalikan AttributeError jika atribut tidak ada dan nilai default tidak ada. ditentukan Untuk apa nama default Getattr OBJ digunakan?Metode getattr() mengembalikan nilai atribut bernama dari suatu objek. Jika tidak ditemukan, ini mengembalikan nilai default yang diberikan ke fungsi
Apa yang dilakukan Getattr () dengan Python?Fungsi getattr() mengembalikan nilai atribut yang ditentukan dari objek yang ditentukan . |
