Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example { #a-dict-from-the-previous-example }

In the previous example, we were returning a `dict` from our dependency ("dependable"):

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

But then we get a `dict` in the parameter `commons` of the *path operation function*.

    return (E[]) new Object[capacity];

  /**
   * Inserts the specified element at the tail of this queue if it is possible to do so immediately
   * without exceeding the queue's capacity, returning {@code true} upon success and throwing an
   * {@code IllegalStateException} if this queue is full.
   *
   * @param e the element to add
   * @return {@code true} (as specified by {@link Collection#add})
