* Jeśli nie rozumiesz pytania, poproś o więcej **szczegółów**.

### Odtwórz problem

W większości przypadków problem wynika z **autorskiego kodu** osoby pytającej.

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

### Das Problem reproduzieren

In den meisten Fällen und bei den meisten Fragen ist etwas mit dem von der Person erstellten **eigenen Quellcode** los.

In vielen Fällen wird nur ein Fragment des Codes gepostet, aber das reicht nicht aus, um **das Problem zu reproduzieren**.

### Reproduce the problem

For most of the cases and most of the questions there's something related to the person's **original code**.

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

But, sadly, you get nothing useful:

### Add types

Let's modify a single line from the previous version.

We will change exactly this fragment, the parameters of the function, from:

```Python
    first_name, last_name
```

to:

```Python
    first_name: str, last_name: str
```

That's it.

Those are the "type hints":

Maar helaas krijg je niets bruikbaars:

### Types toevoegen

Laten we een enkele regel uit de vorige versie aanpassen.

We zullen precies dit fragment, de parameters van de functie, wijzigen van:

```Python
    first_name, last_name
```

naar:

```Python
    first_name: str, last_name: str
```

Dat is alles.

Dat zijn de "type hints":

		// - All field should be empty except Host and Path.
		if !((u.Scheme == "http" || u.Scheme == "https") &&
			u.User == nil && u.Opaque == "" && !u.ForceQuery && u.RawQuery == "" && u.Fragment == "") {
			return ep, fmt.Errorf("invalid URL endpoint format")
		}

		var port string
		host, port, err = net.SplitHostPort(u.Host)
		if err != nil {
