It declares an optional query parameter `q` as a `str`, and then it just returns it.

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

        This means for example that adding pluginA:goal2 to pre-existing (pluginA:goal1, pluginB:goal) will lead to (pluginA:goal1, pluginA:goal2, pluginB:goal)

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).

**FastAPI** provides several tools to help you deal with **Security** easily, rapidly, in a standard way, without having to study and learn all the security specifications.

But first, let's check some small concepts.

## In a hurry? { #in-a-hurry }

     * easier, we pick out the top SIGNIFICAND_BITS + 2 bits, so we have one to help us round up or

     *
     * It helps to consider the real number signif = absX * 2^(SIGNIFICAND_BITS - exponent).

Mais il y a encore de nombreuses améliorations et fonctionnalités à venir.

**FastAPI** a un grand avenir devant lui.
