What are the main types of iterators in Python?
In Python, the main types of iterators are list iterators, tuple iterators, and dictionary iterators. Each type allows you to traverse through its respective data structure.
How do list iterators differ from dictionary iterators?
List iterators allow you to access elements in a sequential manner, while dictionary iterators provide access to keys, values, or key-value pairs.
Can you give an example of using a list iterator?
Sure! You can create a list iterator using the iter()
function and then use next()
to access elements one by one.
What about performance differences between these iterators?
List iterators are generally faster for sequential access, while dictionary iterators are optimized for key lookups, making them faster for certain operations.
