How do you use belong?

To use the "belong" method in Python, you can check if an element belongs to a specified list or dictionary. For example, you can use the "in" keyWord to check if an element is in a list. Here's an example:

<code class="language-python">my_list = [1, 2, 3, 4, 5]
if 3 in my_list: print("Yes, 3 belongs to the list.")
</code>

Similarly, you can use the "in" keyWord to check if a key belongs to a dictionary.
