GOIOS_DEV_ID, GOIOS_TEAM_ID and GOIOS_APP_ID. The detect.go program in this directory will
attempt to auto-detect suitable values. Run it as

	go run detect.go

which will output something similar to

	export GOIOS_DEV_ID="iPhone Developer: ******@****.*** (XXXXXXXX)"
	export GOIOS_APP_ID=YYYYYYYY.some.bundle.id
	export GOIOS_TEAM_ID=ZZZZZZZZ

Así que, puedes usar `user_agent` como normalmente lo harías en código Python, en lugar de necesitar capitalizar las primeras letras como `User_Agent` o algo similar.

Si por alguna razón necesitas desactivar la conversión automática de guiones bajos a guiones, establece el parámetro `convert_underscores` de `Header` a `False`:

        String url = "smb://server/IPC$/pipeName"; // Corrected URL for named pipe
        int pipeType = 1;
        SmbPipeResource mockSmbPipeResource = mock(SmbNamedPipe.class);

        // Similar to testGetSmbResource, we cannot directly mock `new SmbNamedPipe()`.
        // We verify that no exception is thrown for a valid URL and that it attempts to create an SmbNamedPipe.

Sadece `str` yerine `str | None` kullanmak, aslında değer `None` olabilecekken her zaman `str` olduğunu varsaydığınız hataları editörün yakalamanıza yardımcı olur.

### Tip olarak sınıflar { #classes-as-types }

Bir sınıfı da bir değişkenin tipi olarak bildirebilirsiniz.

Örneğin, adı olan bir `Person` sınıfınız olsun:

        companies, or even industries — utilities useful for a sizable proportion of all Java
        programmers everywhere. If you can give enough detail such that any of us can imagine coming
        across a similar need in our own work, that's extremely helpful in studying how broadly
        useful the proposed change will be.
