If you use any other tool to manage your installations, like `uv`, Poetry, Pipenv, or others, they all have a way that you can use to define specific versions for your packages.

## Available versions { #available-versions }

# Sub-dependencies { #sub-dependencies }

You can create dependencies that have **sub-dependencies**.

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

## Tags { #tags }

You can add tags to your *path operation*, pass the parameter `tags` with a `list` of `str` (commonly just one `str`):

{* ../../docs_src/path_operation_configuration/tutorial002_py310.py hl[15,20,25] *}

They will be added to the OpenAPI schema and used by the automatic documentation interfaces:

### Tags with Enums { #tags-with-enums }

 * - Workarounds which may affect the way the compilation is performed
 *
 * The compilation workarounds include:
 * - Using JDK internal classes
 * - Using Java standard library APIs that were introduced after the JVM version they are targeting
 *
 * All of these workarounds should be generally avoided, but, with this data we can configure the
 * compile tasks to permit some of these requirements.

    classes are conceptually a part of Guava, but they're in this separate
    artifact so that Android libraries can use them without pulling in all of
    Guava (just as they can use ListenableFuture by depending on the
    listenablefuture artifact).
