# Multiple CLI Options

You can declare a CLI option that can be used multiple times, and then get all the values.

For example, let's say you want to accept several users in a single execution.

For this, use the standard Python `typing.List` to declare it as a `list` of `str`:

{ docs_src/multiple_values/multiple_options/tutorial001_an.py hl[1,7] }

You will receive the values as you declared them, as a `list` of `str`.

Check it:

    // The default value is 'None'
    $ python main.py

    No provided users (raw input = None)
    Aborted!

    // Now pass a user
    $ python main.py --user Camila

    Processing user: Camila

    // And now try with several users
    $ python main.py --user Camila --user Rick --user Morty

    Processing user: Camila
    Processing user: Rick
    Processing user: Morty

## Multiple `float`

The same way, you can use other types and they will be converted by Typer to their declared type:

{ docs_src/multiple_values/multiple_options/tutorial002_an.py hl[7] }

Check it:

    $ python main.py

    The sum is 0

    // Try with some numbers
    $ python main.py --number 2

    The sum is 2.0

    // Try with some numbers
    $ python main.py --number 2 --number 3 --number 4.5

    The sum is 9.5
