You are given a code snippet that contains two blocks of code. The first block checks if a hyphen ('-') is present in the variable `name`. If it is, it performs some operations on the `namespace` variable. The second block constructs a string using the `id_prefix` and `name` variables.

Your task is to complete the missing parts of the code snippet. Specifically, you need to implement the missing code inside the `if` statement that determines the value of the `namespace` variable when a hyphen is present in `name`.

Complete the function `get_namespace(name: str) -> str` that takes a string `name` as input and returns the value of the `namespace` variable based on the following rules:
- If `name` contains a hyphen, the `namespace` should contain all the substrings before the last hyphen (excluding the last hyphen itself). Join these substrings using hyphens and assign it to `namespace`.
- If `name` does not contain a hyphen, `namespace` should be an empty string.

Example:
Input
name = "abc-def-ghi"

Output
"abc-def-"

Input
name = "xyz"

Output
""

Sure, I can help with this. Here's how you can implement the `get_namespace()` function with the given rules:

```python
def get_namespace(name: str) -> str:
    # If 'name' contains a hyphen, extract the substrings before the last hyphen (excluding the last hyphen)
    if '-' in name:
        namespace = ''.join(name.split('-')[:-2]) # exclude the last hyphen
    else:
        # If 'name' doesn't contain a hyphen, return an empty string for 'namespace'
        namespace = ''
    return namespace
```

In the `if` statement of your nested code snippet, you can call this function when a hyphen is present in `name`, like this:

```python
if '-' in name:
    namespace = get_namespace(name)
    # perform operations on namespace
```

This will ensure that the value of `namespace` is calculated based on the given rules. Note that I used `[:-2]` to exclude the last hyphen from the list of substrings in `name.split('-')`.

Sure, I can help you complete the function `get_namespace(name: str) -> str` based on the rules you provided. Here's how you can do it:

```python
def get_namespace(name: str) -> str:
    # Initialize the namespace variable
    namespace = ""

    # Check if a hyphen is present in the name
    if "-" in name:
        # Split the name into substrings using the hyphen as a separator
        name_parts = name.split("-")

        # Take all substrings before the last one
        namespace_parts = name_parts[:-1]

        # Join these substrings using hyphens
        namespace = "-".join(namespace_parts)

    return namespace
```

This function works by first checking if a hyphen is present in the `name` string. If it is, it splits the `name` into substrings using the hyphen as a separator. It then takes all substrings before the last one, joins them using hyphens, and assigns the result to the `namespace` variable. If `name` does not contain a hyphen, `namespace` remains an empty string.
