In this post, we will illustrate how to use the translate_text() function in the AWS SDK for Python (Boto3).
Environment
$ pip install -U boto3 $ pip list | grep boto3 boto3 1.7.82
Sample code
As stated in the document, the text string is 5,000 bytes. Therefore, if it exceeds 5,000 bytes, an error will occur. Since we assume we won’t be translating long sentences for this example, we will cut down the number of bytes using while to avoid errors.
Amazon Translate | TranslateText
The text to translate. The text string can be a maximum of 5,000 bytes long. Depending on your character set, this may be fewer than 5,000 characters.
From English to Japanese
while len(text) > 5000: text = text[:-1]
From Japanese to English
while len(text.encode('utf-8')) > 5000:
text = text[:-1]
Execution
From Japanese to English
text = """自然で正確な言語翻訳"""
Execution result
$ python amazon-translate.py Natural and accurate language translation
From English to Japanese
text = """Natural and accurate language translation"""
Execution result
$ python amazon-translate.py 自然で正確な言語翻訳
