Dekorator adalah alat yang sangat kuat dan berguna di Python karena memungkinkan pemrogram untuk mengubah perilaku suatu fungsi atau kelas. Dekorator memungkinkan kita membungkus fungsi lain untuk memperluas perilaku fungsi yang dibungkus, tanpa mengubahnya secara permanen. Namun sebelum mendalami dekorator, mari kita pahami beberapa konsep yang akan berguna dalam mempelajari dekorator Show
Objek Kelas SatuDalam Python, fungsi adalah objek kelas satu yang berarti bahwa fungsi dalam Python dapat digunakan atau diteruskan sebagai argumenProperti fungsi kelas satu
Pertimbangkan contoh di bawah ini untuk pemahaman yang lebih baik Contoh 1. Memperlakukan fungsi sebagai objek. Python3

Fungsi bagian dalam mengambil argumen sebagai *args dan **kwargs yang berarti bahwa tupel argumen posisi atau kamus argumen kata kunci dapat diteruskan dengan panjang berapa pun. Ini membuatnya menjadi dekorator umum yang dapat mendekorasi fungsi yang memiliki sejumlah argumen Apa itu dekorator metode Python?Dekorator adalah pola desain dalam Python yang memungkinkan pengguna menambahkan fungsionalitas baru ke objek yang sudah ada tanpa mengubah strukturnya . Dekorator biasanya dipanggil sebelum definisi fungsi yang ingin Anda hias.
Bagaimana Anda menulis kelas dekorator dengan Python?Metode Instance “fun1” di dalam Kelas A memanggil fungsi dekorator “Dekorator” di dalam Kelas B “fun2”. Metode Instance memanggil fungsi dekorator Kelas A. Untuk menggunakan dekorator Kelas A, kita harus menggunakan nama Kelas di mana ada dekorator itu sebabnya kita menggunakan “@A. Dekorator” di sini.
Apa sintaks yang benar untuk menggunakan dekorator?Dekorator menggunakan sintaks khusus dalam JavaScript, di mana mereka diawali dengan simbol @ dan ditempatkan tepat sebelum kode didekorasi .
Apa contoh dekorator di Python?Dengan Python, kita juga bisa mengembalikan fungsi sebagai nilai kembalian. Misalnya, def salam(nama). def halo(). kembalikan "Halo, " + nama + ". " return halo sapa = salam("Atlantis") print(sapa()) # prints "Halo, Atlantis. " # Keluaran. Halo, Atlantis. |
