which is a fitness factor for a lossless data compression.

Pre-compressed input typically compresses in excess of 2GiB/s per core,
so performance impact should be minimal even if precompressed data is re-compressed.
Decompressing incompressible data has no significant performance impact.

Below is a list of common files and content-types which are typically not suitable for compression.

### Walidacja

* Walidacja większości (lub wszystkich?) **typów danych** Pythona, w tym:
    * Obiektów JSON (`dict`).
    * Tablic JSON (`list`) ze zdefiniowanym typem elementów.
    * Pól tekstowych (`str`) z określeniem minimalnej i maksymalnej długości.
    * Liczb (`int`, `float`) z wartościami minimalnymi, maksymalnymi, itp.

* Walidacja bardziej egzotycznych typów danych, takich jak:
    * URL.
    * Email.
    * UUID.

Często pytający umieszczają tylko fragment kodu, niewystarczający do **odtworzenia problemu**.

In many cases they will only copy a fragment of the code, but that's not enough to **reproduce the problem**.

* You can ask them to provide a <a href="https://stackoverflow.com/help/minimal-reproducible-example" class="external-link" target="_blank">minimal, reproducible, example</a>, that you can **copy-paste** and run locally to see the same error or behavior they are seeing, or to understand their use case better.

* **Easy**: Designed to be easy to use and learn. Less time reading docs.
* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
* **Robust**: Get production-ready code. With automatic interactive documentation.
