Hi, I need to know What are iterators in Python
Can I ask you to do a little bit more research before asking on forums?
One critical skill for programming is the ability to search information and learn by yourself.
Please read the glossary entry: Glossary — Python 3.9.2 documentation
and one of the several tutorials you can find about iterators on the web, and feel free to ask here again if you have specific questions about iterators.
