You can define a <abbr title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</abbr> `pattern` that the parameter should match:

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

This specific regular expression pattern checks that the received parameter value:

Podemos **ler** um único herói:

### Atualizar um Hero com `HeroUpdate`

Podemos **atualizar um hero**. Para isso, usamos uma operação HTTP `PATCH`.
