Par exemple, vous pouvez avoir un fichier `main.py` contenant :

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Astuce

Le deuxième argument de [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) est la valeur par défaut à retourner.

### Edit it { #edit-it }

It's a very simple program.

But now imagine that you were writing it from scratch.

At some point you would have started the definition of the function, you had the parameters ready...

But then you have to call "that method that converts the first letter to upper case".

<pre>
[...]Point{{1.5, -3.5}, {0, 0}}     // same as [...]Point{Point{1.5, -3.5}, Point{0, 0}}
[][]int{{1, 2, 3}, {4, 5}}          // same as [][]int{[]int{1, 2, 3}, []int{4, 5}}
[][]Point{{{0, 1}, {1, 2}}}         // same as [][]Point{[]Point{Point{0, 1}, Point{1, 2}}}
map[string]Point{"orig": {0, 0}}    // same as map[string]Point{"orig": Point{0, 0}}

            continue
        missing_paths.append(p)
    print("Paths to skip:")
    for p in skipped_paths:
        print(f"  - {p}")
    print(f"Total paths to skip: {len(skipped_paths)}")
    print("Paths to process:")
    for p in missing_paths:
        print(f"  - {p}")
    print(f"Total paths to process: {len(missing_paths)}")
    for p in missing_paths:
        print(f"Translating: {p}")

```python
#Function declaration
def hello_world():# Print greeting
    print("Hello, world!")  #Print greeting without space after hash
```

```console
//Function declaration
def hello_world():// Print greeting
    print("Hello, world!")  //Print greeting without space after slashes
```

Vous essayez alors avec l'ami de toujours des programmeurs, l'autocomplétion de l'éditeur.

Vous tapez le premier paramètre de la fonction, `first_name`, puis un point (`.`) et appuyez sur `Ctrl+Espace` pour déclencher l'autocomplétion.

Mais, malheureusement, vous n'obtenez rien d'utile :

### Ajouter des types { #add-types }

```python
#Function declaration
def hello_world():# Print greeting
    print("Hello, world!")  #Print greeting without space after hash
```

```console
//Function declaration
def hello_world():// Print greeting
    print("Hello, world!")  //Print greeting without space after slashes
```
