Simple Translator

Project Overview

This Simple Translator project is a Python-based application that provides reliable text translation between multiple languages. Built with both command-line and interactive modes, the application uses external translation APIs while implementing smart caching to improve performance and reduce unnecessary API calls.

Interactive Demo

Try the translator below by entering text and selecting your desired language:

Translate to:

Translated text will appear here.

Features

Multiple Languages

Support for over 100 languages using Google Translate's API.

Intelligent Caching

Stores previous translations to reduce API calls and improve performance.

Dual Interface

Both interactive mode and command-line support for flexible usage.

Save Translations

Option to save translation history to a text file for future reference.

Technical Implementation

The core of the translator is built around efficient API usage and caching:

# Translation function with caching for improved performance
def translate_text(text, dest_language):
    # Check if translation is in cache
    if (text, dest_language) in cache:
        return cache[(text, dest_language)]
    
    translator = Translator()
    translated = translator.translate(text, dest=dest_language)
    
    # Store translation in cache
    cache[(text, dest_language)] = translated.text
    return translated.text
            

Welcome Screen

The app starts with a welcome screen where users can enter the text they want to translate and select the target language. The interface is designed to be straightforward and easy to use.

Translation

Once the user enters the text and selects the target language, the app uses a translation API to fetch the translated text and displays it on the screen. The app supports multiple languages.

Key Features

Language Detection: Automatically detects the source language of input text
Translation Memory: Caches recent translations to improve response time
Batch Processing: Translate multiple texts at once in command-line mode
Error Handling: Robust error handling for network issues and API limitations

How to Use

Interactive Mode:

Launch the application with python Translator.py
Enter the text you want to translate
Select the target language from the menu
View the translation and optionally save it to history

Command-Line Mode:

python Translator.py -t "Hello world" -d es  # Translates "Hello world" to Spanish
            

The application's flexibility makes it useful for casual translations, language learning, and integration into other scripts or workflows.
