## What will be covered in this Blog

```python
1. Translator Introduction
2. What is Googletrans?
3. Create a Translator with Python
```

## Translator Introduction:

The Dictionary definition: 

> The definition of a **translator** is someone who helps people who speak different languages to communicate or who takes something (such as a speech or a book) in one language and who puts it into a different language for people to **understand**.

If you wish to know more about it, you can refer to [Translation Wikipedia Page](https://en.wikipedia.org/wiki/Translation). Use this link to navigate to the GIF's Wikipedia Page.

## What is Googletrans?

Googletrans is a **free** and **unlimited** python library that implemented Google Translate API. This uses the [Google Translate Ajax API](https://translate.google.com/) to make calls to such methods as detect and translate.

- Fast and reliable - it uses the same servers that translate.google.com uses
- Auto language detection
- Bulk translations
- Customizable service URL
- Connection pooling (the advantage of using requests.Session)
- HTTP/2 support

If you wish to know more about it, you can refer to [Googletrans Documentation](https://py-googletrans.readthedocs.io/en/latest/). Use this link to navigate to the documentation.

Now that you are aware of Translator and Googletrans basics, we can move forward to the coding section. 

## Time to code!

You can find all the code at my [GitHub Repository](https://github.com/ayushi7rawat/Youtube-Projects/tree/master/Build%20a%20translater). **Drop a star** if you find it useful.

### Installing Googletrans 

Open your terminal and run the following command

```python
pip install googletrans
```

Now that we have the package, we are ready to import it in our python script.

```python
from googletrans import Translator
```

Let's store some text that we will use for translation. You can use any text segment of your choice. I am using of one of my favourite poem [**Daffodils**](https://www.poetryfoundation.org/poems/45521/i-wandered-lonely-as-a-cloud) by **WILLIAM WORDSWORTH**. Let's store it in `text`. It's the last stanza of the poem. 

The language I am using is `French`. You can choose any language of your choice.

You can even take the text as a user input if you like, so you wont have to make changes in your program every time you wish to use the translator.

```python
text = '''  Pour souvent, quand sur mon canapé je mens
D'humeur vacante ou songeuse,
Ils clignotent sur cet œil intérieur
Quel est le bonheur de la solitude;
Et puis mon cœur se remplit de plaisir,
Et danse avec les jonquilles. '''
```

Let's create an instance of Translator to use. 

```python
translator = Translator()
```

This uses the [Google Translate Ajax API](https://translate.google.com/) to make calls to such methods as detect and translate. Now, let's call the `detect` method on `translator` and pass in our data stored in `text` and store it in `lang`. 

```python
lang = translator.detect(text)
print(lang)
```

 Now let's `print` it out.

- `lang=fr` means the detected language is French.
- `confidence=0.9365149` is how much percentage the translator is confident about the language detection.

```python
Detected(lang=fr, confidence=0.9365149)
```

Once done, let's move forward and actually translate it. I am calling the `translate` method here on `translator` and passing two parametrs.

- `text`: our data in original language
- `dest`: our destination language

Now, to refer the other language codes you can refer to the [google language documentation](https://cloud.google.com/translate/docs/languages)

**NOTE:** If you do not specify any destination language, it will automatically switch to the default one i.e. `English`.

```python
res = translator.translate(text, dest = 'en')
```

At last, let's verify it by printing our `res`.

```python
Often when on my couch I lie
In a vacant or pensive mood,
They blink on that inner eye
What is the happiness of solitude;
And then my heart fills with pleasure,
And dance with the daffodils.
```

This is how the conversion is done. This is all about the **creating a Translator with Python**. That's it! simple, isn't it? Hope this tutorial has helped.

You can play around with the library and explore more features and even make use of Python GUI using Tkinter.
