ก่อนอื่นเช็คโมดูล num2words กันก่อน
โค้ด: เลือกทั้งหมด
pip show num2wordsตัวอย่างผลที่ได้
Name: num2words
Version: 0.5.6
Summary: Modules to convert numbers to words. Easily extensible.
Home-page: https://github.com/savoirfairelinux/num2words
Author: Savoir-faire Linux inc.
Author-email: [email protected]
License: LGPL
Location: /usr/local/lib/python3.8/dist-packages
ถ้าได้เวอร์ชั่นต่ำกว่า 0.5.10
วิธีแก้ทำได้สองวิธีคือ
1. ถ้าไม่สามารถอัพเกรด num2words เป็นเวอร์ชั่นล่าสุดได้ ให้สร้างไฟล์ lang_TH.py ไว้ใน folder ของโมดูล และ เอาค่านี้ใส่ไว้ และ เพิ่มให้เรียกใช้ในไฟล์ __init__.py

2. อัพเกรด num2words เป็นเวอร์ชั่นล่าสุด ด้วยคำสั่ง
โค้ด: เลือกทั้งหมด
pip3 install --upgrade num2wordsแล้วเข้าไปดูใน folder
/usr/local/lib/python3.8/dist-packages/num2words
เพื่อเช็คไฟล์ lang_TH.py
เท่านี้ก็สามารถเปลี่ยนคำอ่านค่าเงินเป็นภาษาไทย เงินบาทได้แล้ว
