These types that have internal types are called "**generic**" types. And it's possible to declare them, even with their internal types.

To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.

#### Newer versions of Python { #newer-versions-of-python }

But now, imagine you are again in the middle of creating that function, but with type hints.

Tại cùng một điểm, bạn thử kích hoạt autocomplete với `Ctrl+Space` và bạn thấy:

Với cái đó, bạn có thể cuộn, nhìn thấy các lựa chọn, cho đến khi bạn tìm thấy một "tiếng chuông":

	var srcEOF, tgtEOF bool

	srcSha256 := sha256.New()
	tgtSha256 := sha256.New()

	for {
		srcSha256.Reset()
		tgtSha256.Reset()

		srcEOF = !srcOk
		tgtEOF = !tgtOk

		// No objects from source AND target: Finish
		if srcEOF && tgtEOF {

		if !srcEOF && srcCtnt.Err != nil {
			log.Fatal(srcCtnt.Err)

        sval = null;
    }

    private boolean processEOF() {
        if (peekc < 0) {
            ttype = TT_EOF;
            return true;
        }
        if (peekc == NEED_CHAR) {
            peekc = read();
            if (peekc < 0) {
                ttype = TT_EOF;
                return true;
            }
        }
        return false;
    }

Diese Typen mit inneren Typen werden „**generische**“ Typen genannt. Es ist möglich, sie mit ihren inneren Typen zu deklarieren.

Um diese Typen und die inneren Typen zu deklarieren, können Sie Pythons Standardmodul `typing` verwenden. Es existiert speziell für die Unterstützung dieser Typhinweise.

Проверьте эту функцию, она уже имеет аннотации типов:
