To extract attributes of elements in Beautiful Soup, use the `[~]` notation. For instance, `el["id"]` retrieves the value of the `id` attribute.

# Example

Consider the following HTML document:

``` my_html = """ <p id="alex" age="10">Alex</p> <p id="bob" age="20">Bob</p>"""soup = BeautifulSoup(my_html) ```

To extract the value of attributes `id` and `age`:

``` for el in soup.find_all("p"): print(el["id"] + " - " + el["age"]) alex - 10bob - 20 ```
WARNING

An error will be thrown if the element does not contain the specified attribute

In order to avoid the error, you can check whether an element contains a specific attribute by calling `has_attr(~)` first:

``` for el in soup.find_all("p"): if el.has_attr("age"): print(el.attrs["age"]) ```
