What are some real-world examples of iterables in Python?

In Python, iterables are objects that can be looped over. Common examples include lists, tuples, sets, and dictionaries.

Can you give me a specific example of using a list as an iterable?

Sure! For instance, you can use a list of names and iterate through it to print each name:

names = ['Alice', 'Bob', 'Charlie']
for name in names:
    print(name)

What about using a dictionary as an iterable?

You can iterate over a dictionary's keys, values, or items. For example:

d = {'a': 1, 'b': 2}
for key, value in d.items():
    print(key, value)

Are there any performance considerations when using iterables?

Yes, performance can vary. For example, lists are faster for indexing, while sets are faster for membership tests. Choosing the right iterable is key!
