Eine **virtuelle Umgebung** unterscheidet sich von einer **Umgebungsvariable**.

Eine **Umgebungsvariable** ist eine Variable im System, die von Programmen verwendet werden kann.

Eine **virtuelle Umgebung** ist ein Verzeichnis mit einigen Dateien darin.

### Memory per Process { #memory-per-process }

Now, when the program loads things in memory, for example, a machine learning model in a variable, or the contents of a large file in a variable, all that **consumes a bit of the memory (RAM)** of the server.

Vous écrivez du Python standard avec des types :

```Python
from datetime import date

from pydantic import BaseModel

# Déclarez une variable comme étant une str
# et profitez de l'aide de l'éditeur dans cette fonction
def main(user_id: str):
    return user_id


# Un modèle Pydantic
class User(BaseModel):
    id: int
    name: str

variables from your model are also going to be untrusted. That means that if
your code interacts with the filesystem, network, etc. and uses checkpointed
variables as part of those interactions (ex: using a string variable to build a
filesystem path), a maliciously created checkpoint might be able to change the
targets of those operations, which could result in arbitrary
read/write/executions.

## Variável de Ambiente `PATH` { #path-environment-variable }

Existe uma variável de ambiente **especial** chamada **`PATH`** que é usada pelos sistemas operacionais (Linux, macOS, Windows) para encontrar programas para executar.

```sh
openssl genrsa -aes256 -passout pass:PASSWORD -out private.key 2048
```

**Note:** When using a password-protected private key, the password must be provided through the environment variable `MINIO_CERT_PASSWD` using the following command:

```sh
export MINIO_CERT_PASSWD=<PASSWORD>
```
