La fonction :

* Prend un `first_name` et un `last_name`.
* Convertit la première lettre de chaque paramètre en majuscules grâce à `title()`.
* Concatène les résultats avec un espace entre les deux.

### Limitations

C'est un programme très simple.

Mais maintenant imaginez que vous l'écriviez de zéro.

*   Add a `tf.distribute.cluster_resolver.TPUClusterResolver.connect` API to
    simplify TPU initialization.
*   Add `tf.distribute.Strategy.gather` and
    `tf.distribute.ReplicaContext.all_gather` methods to gather and concatenate
    `tf.distribute.DistributedValues` across workers and devices.

### `tf.keras`:

*   Introduces experimental preprocessing layers API

The function does the following:

* Takes a `first_name` and `last_name`.
* Converts the first letter of each one to upper case with `title()`.
* <abbr title="Puts them together, as one. With the contents of one after the other.">Concatenates</abbr> them with a space in the middle.

### Edit it { #edit-it }

It's a very simple program.

A função faz o seguinte:

* Converte a primeira letra de cada uma em maiúsculas com `title()`.
* <abbr title = "Agrupa-os, como um. Com o conteúdo de um após o outro.">Concatena</abbr> com um espaço no meio.

### Edite-o { #edit-it }

É um programa muito simples.

Mas agora imagine que você estava escrevendo do zero.

<p>
Strings can be concatenated using the <code>+</code> operator
or the <code>+=</code> assignment operator:

<pre>
s := "hi" + string(c)
s += " and good bye"
