## Read env vars in Python { #read-env-vars-in-python }

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

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

/// tip

For example, in the URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...the query parameters are:

* `skip`: with a value of `0`
* `limit`: with a value of `10`

As they are part of the URL, they are "naturally" strings.

But when you declare them with Python types (in the example above, as `int`), they are converted to that type and validated against it.

    @DisplayName("Should correctly initialize MsrpcSamrOpenAlias with provided parameters")
    void testConstructorInitialization() {
        // Given
        int access = 0x01; // Example access value
        int rid = 123; // Example RID value

        // When
        MsrpcSamrOpenAlias msrpcSamrOpenAlias = new MsrpcSamrOpenAlias(mockDomainHandle, access, rid, mockAliasHandle);

        // Then

   * header to create the request URL.

   * For HTTP proxy requests this will be either an absolute-form string like
   * `http://example.com/index.html` (HTTP proxy) or an authority-form string like
   * `example.com:443` (HTTPS proxy).
   *
   * For OPTIONS requests, this may be an asterisk, `*`.
