Daftar sama seperti array, dideklarasikan dalam bahasa lain. Daftar tidak harus selalu homogen yang menjadikannya alat yang paling kuat di Python. Daftar tunggal mungkin berisi Tipe Data seperti Integer, String, serta Objek. Daftar dapat berubah, dan karenanya, dapat diubah bahkan setelah dibuat Show Namun, Pernahkah Anda bertanya-tanya tentang cara mendeklarasikan daftar kosong dengan Python? . e. baik dengan menggunakan Kami biasanya melakukan tugas untuk mendapatkan nilai indeks tertentu dan menugaskan variabel darinya. Pendekatan umum yang kami ikuti adalah mengekstrak setiap elemen daftar dengan indeksnya dan kemudian menugaskannya ke variabel. Pendekatan ini membutuhkan lebih banyak baris kode. Mari kita bahas cara-cara tertentu untuk melakukan tugas ini secara kompak untuk meningkatkan keterbacaan. Metode #1. Menggunakan pemahaman daftar Dengan menggunakan pemahaman daftar seseorang dapat mencapai tugas ini dengan mudah dan dalam satu baris. Kami menjalankan loop untuk indeks tertentu di RHS dan menugaskannya ke variabel yang diperlukan. Python3

Berikut tampilan daftarnya. NamaDaftar = [ItemDaftar,ItemDaftar1,ItemDaftar2,ItemDaftar3,. ] Perhatikan bahwa daftar dapat memiliki/menyimpan tipe data yang berbeda.
Bisakah Anda memasukkan variabel ke dalam daftar Python?Karena sebuah daftar dapat berisi variabel Python apa saja , bahkan dapat berisi daftar lainnya.
Bagaimana Anda mendeklarasikan variabel dalam daftar?Daftar dalam Python dapat dibuat hanya dengan menempatkan urutan di dalam tanda kurung siku []. Untuk mendeklarasikan daftar kosong cukup tetapkan variabel dengan tanda kurung siku . Konstruktor list() digunakan untuk membuat list dengan Python.
Bisakah Anda memiliki variabel dalam daftar?Variabel daftar menyimpan daftar nilai (misalnya, login atau kata sandi) untuk digunakan dalam skenario . Setiap variabel daftar menentukan urutan, di mana pengguna virtual mengakses nilai daftar. |
