What are some practical use cases for iterables in Python?

Iterables in Python are used in various scenarios, such as data processing, looping through collections, and more. For example, you can use iterables to read large files line by line without loading the entire file into memory.

Can you give me an example of using iterables with a for loop?

Sure! Here's a simple example: you can use a for loop to iterate over a list of numbers and print each one:

numbers = [1, 2, 3, 4, 5]
for number in numbers:
    print(number)

What about using iterables with functions like map or filter?

Great question! You can use map to apply a function to all items in an iterable. For example:

squared = list(map(lambda x: x**2, numbers))

And filter can be used to filter items based on a condition:

even_numbers = list(filter(lambda x: x % 2 == 0, numbers))
