How to make a python class iterable
Article Introduction：In order to make Python classes iterable, the \_\_iter\_\_ and \_\_next\_\_ methods need to be implemented. 1. Implement \_\_iter\_\_Return an iterator object (usually itself or new object); 2. Define the \_\_next\_\_ method in the iterator to control each return value and stop conditions; 3. The iterator can be classified separately to support multiple independent loops; 4. Pay attention to throwing StopIteration to avoid infinite loops and ensure that the state is managed correctly.

How to make an object iterable in Python?
Article Introduction：In Python, to make an object iterable, you need to implement the __iter__ method and return an iterator with the __next__ method; the specific steps are as follows: 1. Define the __iter__ method in the class, and return itself or another iterator object that implements the __next__ method; 2. If you use the generator function to implement __iter__, you can automatically manage the state and iterative logic through the yield keyword; 3. Every time you call iter(), you should return a new iterator to ensure that multiple loops do not interfere with each other, and throw a StopIteration exception at the end of the iteration to prevent infinite loops.
