What are some common uses of iterators in Python?

Iterators in Python are commonly used for looping through data structures like lists, tuples, and dictionaries. They allow for efficient data traversal without needing to load the entire structure into memory.

Can you give me an example of how to use an iterator?

Sure! Here's a simple example: you can create an iterator from a list using the iter() function and then use next() to access elements one by one.

What about using iterators with custom objects?

Great question! You can make your custom objects iterable by implementing the __iter__() and __next__() methods, allowing you to define how your object should be traversed.

Are there any built-in functions that work well with iterators?

Yes! Functions like map(), filter(), and zip() work seamlessly with iterators, allowing for powerful data manipulation.
