Python Baidu Translation API implements Danish translation

Overview:
With the development of globalization, communication between languages ​​has become more and more important. In order to meet the translation needs between different languages, many Internet companies provide a series of translation interfaces. Baidu Translation API is one of them, which provides a simple and easy-to-use interface that can easily realize translation interaction in multiple languages. This article will introduce how to use Python Baidu Translation API to implement Danish translation, and attach corresponding code examples.

Environment configuration:
Before using Baidu Translation API, we need to perform some necessary environment configuration. First, we need to register and create an application on Baidu Developer Platform to obtain an API key. Secondly, we need to install the Python module requests through which we can send HTTP requests and receive responses. You can install the requests module through the following command:

pip install requests

Code example:
The following is a code example that uses the Python Baidu Translation API to implement Danish translation:

import requests
import hashlib
import random
import json

def translate(text, from_lang, to_lang):
    appid = 'your_appid'  # 替换为自己的appid
    secret_key = 'your_secret_key'  # 替换为自己的secret_key

    api_url = 'http://api.fanyi.baidu.com/api/trans/vip/translate'

    # 生成随机的salt值
    salt = random.randint(32768, 65536)

    # 计算签名
    sign_str = appid + text + str(salt) + secret_key
    sign = hashlib.md5(sign_str.encode()).hexdigest()

    # 发送HTTP请求
    params = {
        'q': text,
        'from': from_lang,
        'to': to_lang,
        'appid': appid,
        'salt': salt,
        'sign': sign
    }
    response = requests.get(api_url, params=params)
    result = json.loads(response.text)

    # 解析翻译结果
    translated_text = result['trans_result'][0]['dst']

    return translated_text

# 调用翻译函数
text = 'Hello, world!'
translated_text = translate(text, 'auto', 'da')
print('翻译前：', text)
print('翻译后：', translated_text)

Explanation:
Next, let us give some explanations to the above code.

Lines 9 and 10 need to replace your_appid and your_secret_key respectively with the appid and secret_key you obtained when registering the application on Baidu Developer Platform.

Line 14 generates a random salt value by calling the random.randint() method, with the value range being [32768, 65536).

Line 17 calculates the signature. The signature algorithm requires appid text salt secret_key to be spliced ​​into a string in order, and then MD5 calculation is performed on the string to obtain the signature .

Line 20 sends an HTTP request through the requests.get() method and parses the returned response into JSON format.

Line 23 extracts the translated text from the translation results.

Finally, call the translate() function on line 27, and pass in the text to be translated, the source language and the target language as parameters for translation. Then output the original text and translation on lines 29 and 30.

Summary:
This article introduces how to use Python Baidu Translation API to implement Danish translation. By using Baidu Translation API, we can easily implement translation functions between multiple languages ​​and facilitate language communication. Everyone can make corresponding adjustments and expansions according to their own needs to achieve more interesting functions.
