Detect

This package includes the ability to detect the language of the texts. Let’s try this time by taking text from the user :

text = input(“Enter your text “)
# to get text from user
detector = google_translator() 
detected_language= detector.detect(text)
print(detected_language)

After entering the text we get this output :

Translate the text by using google-trans-new

We can see how we integrate it in a very simple application. We can create an application that translates the user uploaded .txt file into English and creates a new .txt file. Let’s see how we can create this project on Colab.

We use the pip install command again to install the package.

pip install google_trans_new

Import the necessary libraries :

from google_trans_new import google_translator
from google.colab import files 
#to upload file on Colab

Upload the text.txt named file

After uploading, translate text to english :

upload_file = open(‘text.txt’, ‘r’)
#to open the uploaded file
text= upload_file.read()
translator = google_translator()
translated_text = translator.translate(text, lang_tgt=’en’)
#to translate text
upload_file.close() 
#to close the file

Create new .txt file

translated_file = open (‘translated_text.txt’,’w’)
#to create new file and write to the file
translated_file.write (translated_text)
translated_file.close()

We can see the created file from here :
