Bagaimana Anda mendefinisikan daftar string dengan python?

Daftar Python seperti array berukuran dinamis, dideklarasikan dalam bahasa lain (vektor dalam C++ dan ArrayList di Jawa). Dalam bahasa sederhana, daftar adalah kumpulan hal-hal, diapit [ ] dan dipisahkan dengan koma.

Daftar adalah tipe data urutan yang digunakan untuk menyimpan kumpulan data. Tuples dan String adalah tipe lain dari tipe data sequence

Contoh daftar dengan Python

Di sini kami membuat Daftar Python menggunakan []

Daftar adalah wadah paling sederhana yang merupakan bagian integral dari bahasa Python. 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

Membuat Daftar dengan Python

Daftar dengan Python dapat dibuat hanya dengan menempatkan urutan di dalam tanda kurung siku[]. Tidak seperti Sets, daftar tidak memerlukan fungsi bawaan untuk membuat daftar.

Catatan. Tidak seperti Set, daftar mungkin berisi elemen yang dapat diubah.

Menambahkan Elemen ke Daftar Python

Metode 1. Menggunakan append() metode

Elemen dapat ditambahkan ke Daftar dengan menggunakan fungsi append() bawaan. Hanya satu elemen pada satu waktu yang dapat ditambahkan ke daftar dengan menggunakan metode append(), untuk penambahan beberapa elemen dengan metode append(), loop digunakan. Tupel juga dapat ditambahkan ke daftar dengan menggunakan metode append karena tupel tidak dapat diubah. Tidak seperti Set, Daftar juga dapat ditambahkan ke daftar yang sudah ada dengan menggunakan metode append()

Mengiris Daftar

Kita bisa mendapatkan substring dan sublist menggunakan sebuah slice. Dalam Daftar Python, ada beberapa cara untuk mencetak seluruh daftar dengan semua elemen, tetapi untuk mencetak rentang elemen tertentu dari daftar, kami menggunakan operasi Slice.

Operasi irisan dilakukan pada Daftar dengan menggunakan tanda titik dua (. ).

Untuk mencetak elemen dari awal hingga penggunaan rentang

Daftar Pemahaman

Pemahaman Daftar Python digunakan untuk membuat daftar baru dari iterable lain seperti tupel, string, array, daftar, dll. Pemahaman daftar terdiri dari tanda kurung yang berisi ekspresi, yang dijalankan untuk setiap elemen bersama dengan perulangan for untuk mengulangi setiap elemen.

Sintaksis

DaftarBaru = [ekspresi(elemen) untuk elemen dalam Daftarlama jika kondisi]
