An Example Script: Translation services

Step 1: Set Up Azure Translator Resource

  • Log in to your Azure portal.
  • Create a Translator resource.
  • Note the endpoint and API key provided.

Step 2: Install Required Libraries

pip install requests

Step 3: Code

import requests

# Replace with your Azure endpoint and API key
endpoint = “<your-endpoint>”
subscription_key = “<your-api-key>”
region = “<your-region>”

# Text to be translated
text = “Hello, how are you?”
target_language = “es” # Spanish

# Construct the API request
url = f”{endpoint}/translate?api-version=3.0&to={target_language}”
headers = {
“Ocp-Apim-Subscription-Key”: subscription_key,
“Ocp-Apim-Subscription-Region”: region,
“Content-Type”: “application/json”
}
body = [{“Text”: text}]

# Send the request
response = requests.post(url, headers=headers, json=body)
translations = response.json()

# Display the translated text
translated_text = translations[0][‘translations’][0][‘text’]
print(f”Original Text: {text}”)
print(f”Translated Text: {translated_text}”)

Output:

Original Text: Hello, how are you?
Translated Text: Hola, ¿cómo estás?
