Modern versions of Python have support for **"asynchronous code"** using something called **"coroutines"**, with **`async` and `await`** syntax.

Let's see that phrase by parts in the sections below:

* **Asynchronous Code**
* **`async` and `await`**
* **Coroutines**

## Asynchronous Code { #asynchronous-code }

   * while not being a public suffix itself. For example, returns {@code true} for {@code
   * www.google.com}, {@code foo.co.uk} and {@code myblog.blogspot.com}, but not for {@code com},
   * {@code co.uk}, {@code google.invalid}, or {@code blogspot.com}.
   *
   * <p>This method can be used to determine whether it will probably be possible to set cookies on

 * <i>implemented</i>, the design of the {@code Multimap} API is based on the <i>second</i> form.
 * So, using the multimap shown above as an example, the {@link #size} is {@code 3}, not {@code 2},
 * and the {@link #values} collection is {@code [1, 2, 3]}, not {@code [[1, 2], [3]]}. For those
 * times when the first style is more useful, use the multimap's {@link #asMap} view (or create a
 * {@code Map<K, Collection<V>>} in the first place).
