Apa fungsi random.choice 1 pada python

Bilangan acak bukan berarti angka yang akan menjadi berbeda setiap saat. Acak artinya sesuatu yang tidak bisa diprediksi secara logis.

Komputer mengerjakan program, dan program adalah sekumpulan instruksi yang pasti. Jadi sebuah program berarti harus ada algoritma untuk menghasilkan bilangan acak.

Jika ada program untuk menghasilkan bilangan acak maka dapat diprediksi, sehingga tidak benar-benar acak.

Bilangan acak yang dihasilkan melalui algoritma pembangkitan disebut pseudo random.

Bisakah kita membuat bilangan yang benar-benar acak?

Jawabannya bisa. Untuk menghasilkan bilangan yang benar-benar acak pada komputer, kita perlu mendapatkan data acak dari beberapa sumber luar. Sumber luar ini umumnya adalah penekanan tombol, gerakan mouse, data di jaringan, dll.

Kita tidak memerlukan bilangan yang benar-benar acak, kecuali yang terkait dengan keamanan (misalnya kunci enkripsi) atau dasar aplikasinya adalah keacakan (misalnya roda roulette digital).

Dalam tutorial ini kita akan menggunakan bilangan acak semu.

Menghasilkan Bilangan Acak

NumPy menawarkan modul random untuk bekerja dengan bilangan acak.

Contoh
Hasilkan bilangan bulat acak dari 0 hingga 100

from numpy import random x = random.randint(100) print(x)

Hasilkan Bilangan acak Float

Metode rand() pada modul random mengembalikan float acak antara 0 dan 1.

Contoh:
Hasilkan bilangan float acak dari 0 hingga 1

from numpy import random x = random.rand() print(x)

Pada NumPy kita sering bekerja dengan array, dan kita dapat menggunakan dua metode dari contoh di atas untuk membuat array acak.

Bilangan bulat

Metode randint() mengambil parameter ukuran tempat dimana kita dapat menentukan bentuk array.

Contoh:
Hasilkan array 1-D yang berisi 5 bilangan bulat acak dari 0 hingga 100

from numpy import random x=random.randint(100, size=(5)) print(x)

Contoh:
Hasilkan array 2-D dengan 3 baris, setiap baris berisi 5 bilangan bulat acak dari 0 hingga 100

from numpy import random x = random.randint(100, size=(3, 5)) print(x)

Float

Metode rand() juga memungkinkan kita untuk menentukan bentuk array.

Contoh:
Hasilkan array 1-D yang berisi 5 float acak

from numpy import random x = random.rand(5) print(x)

Contoh:
Hasilkan array 2-D dengan 3 baris, setiap baris berisi 5 nomor acak

from numpy import random x = random.rand(3, 5) print(x)

Menghasilkan Bilangan Acak Dari Array

Metode choice() memungkinkan kita untuk menghasilkan nilai acak berdasarkan nilai array.

Metode choice() mengambil array sebagai parameter dan secara acak mengembalikan salah satu nilai.

Contoh:
Kembalikan salah satu nilai dalam array

from numpy import random x = random.choice([3, 5, 7, 9]) print(x)

Metode choice() juga memungkinkan kita untuk mengembalikan array nilai.

Tambahkan parameter ukuran untuk menentukan bentuk array.

Contoh:
Hasilkan array 2-D yang terdiri dari nilai-nilai dalam parameter array (3, 5, 7, dan 9)

from numpy import random x = random.choice([3, 5, 7, 9], size=(3, 5)) print(x)
