* and in there, find the module `dependencies` (the file at `app/dependencies.py`)...

That works correctly! 🎉

The same way, if we had used three dots `...`, like in:

```Python
from ...dependencies import get_token_header
```

that would mean:

## Investigation { #investigation }

By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

world, because the Go garbage collector is unaware of the memory
allocated by C.  The most important consideration is not to
constrain future implementations, so the rule is that Go code can
hand a Go pointer to C code but must separately arrange for
Go to hang on to a reference to the pointer until C is done with it.

With this, even if you receive a request with duplicate data, it will be converted to a set of unique items.

And whenever you output that data, even if the source had duplicates, it will be output as a set of unique items.

And it will be annotated / documented accordingly too.
