#### List

For example, let's define a variable to be a `list` of `str`.

//// tab | Python 3.9+

Declare the variable, with the same colon (`:`) syntax.

As the type, put `list`.

As the list is a type that contains some internal types, you put them in square brackets:

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006_py39.py!}
```

  /** Guard for waiting takes */
  private final Monitor.Guard notEmpty;

  /** Guard for waiting puts */
  private final Monitor.Guard notFull;

  // Internal helper methods

  /** Circularly increment i. */
  final int inc(int i) {
    return (++i == items.length) ? 0 : i;
  }

  /**
   * Inserts element at current put position, advances, and signals. Call only when occupying
   * monitor.
   */

        map.put("ト", new String[] { "to" });

        map.put("ナ", new String[] { "na" });
        map.put("ニ", new String[] { "ni" });
        map.put("ヌ", new String[] { "nu" });
        map.put("ネ", new String[] { "ne" });
        map.put("ノ", new String[] { "no" });

        map.put("ハ", new String[] { "ha" });

        map.put("フ", new String[] { "hu", "fu" });

	this symbol.

	In the <remote>, # or @ can be used to introduce a symbol version.

	Examples:
	//go:cgo_import_dynamic puts
	//go:cgo_import_dynamic puts puts#GLIBC_2.2.5
	//go:cgo_import_dynamic puts puts#GLIBC_2.2.5 "libc.so.6"

	A side effect of the cgo_import_dynamic directive with a
	library is to make the final binary depend on that dynamic
