GetLexicon

Kode Python berikut menggunakan AWS SDK for Python (Boto) untuk mengambil semua leksikon yang disimpan di Wilayah. AWS Contoh menerima nama leksikon sebagai parameter baris perintah dan mengambil leksikon itu saja, mencetak jalur tmp di mana ia telah disimpan secara lokal.

Contoh kode berikut menggunakan kredensi default yang disimpan dalam file konfigurasi AWS SDK. Untuk informasi tentang membuat file konfigurasi, lihatLangkah 2.1: Mengatur AWS CLI.
