Python Baidu Translation API implements Vietnamese translation

Introduction:
As global communication becomes closer and closer, language translation becomes more and more important. In the computer field, there are many automatic translation tools that can help us understand and translate different languages. Baidu Translation API is one of the commonly used automatic translation tools, which provides rich language support.

This article will introduce how to use the Python programming language and combine with Baidu Translation API to achieve Vietnamese translation. We will obtain the key of Baidu Translation API and write Python code to realize the function of translating Chinese to Vietnamese.

Step 1: Obtain Baidu Translation API Key
First, we need to go to Baidu Translation Open Platform (http://api.fanyi.baidu.com/) to register an account and create a new application to get the API key. After registering an account and logging in, we can click "My Application", then choose to create a new application and fill in the relevant information. After creation, we can find our application in the application list and obtain the API key.

Step 2: Install the necessary libraries
We need to install the requests library and the json library in order to send HTTP requests and process the returned JSON data in Python. You can use the following command to install these two libraries:

pip install requests pip install json

Step 3: Write Python code
Next, we will write Python code to implement Chinese to Vietnamese translation. We need to import the requests and json libraries and define a function to implement the translation function.

import requests import json def translate(text): api_url = 'http://api.fanyi.baidu.com/api/trans/vip/translate' from_lang = 'zh' to_lang = 'vie' appid = 'your_appid' secret_key = 'your_secret_key' salt = random.randint(32768, 65536) sign = appid + text + str(salt) + secret_key sign = hashlib.md5(sign.encode()).hexdigest() params = { 'q': text, 'from': from_lang, 'to': to_lang, 'appid': appid, 'salt': str(salt), 'sign': sign } response = requests.get(api_url, params=params) result = json.loads(response.content.decode('utf-8')) if 'trans_result' in result: return result['trans_result'][0]['dst'] else: return None # 测试代码 text = '你好' translated_text = translate(text) print(f"翻译前：{text}") print(f"翻译后：{translated_text}")

In the above code, we first define parameters such as the URL, source language and target language, application ID and key of Baidu Translation API. Then, we calculate the signature based on the parameters and send a GET request to the Baidu Translation API. Finally, we parse the translated text from the returned results.

Step 4: Run the code
Before running the code, please replace "your_appid" and "your_secret_key" in the code with your own API key. Then, execute the code and view the translation results.

翻译前：你好 翻译后：xin chào

Conclusion:
This article introduces how to use the Python programming language combined with Baidu Translation API to achieve Chinese to Vietnamese translation. By obtaining the key of Baidu Translation API and writing the corresponding Python code, we can easily implement the automatic translation function and apply it to different scenarios. I hope this article will be helpful to readers who understand how to use Baidu Translation API to achieve Vietnamese translation.
