Python - Magic Methods and Operator Overloading

Which of the following is the correct way to define an iterator class in Python?

Aclass MyIter: def __next__(self): pass

Bclass MyIter: def next(self): pass

Cclass MyIter: def __iter__(self): return self def __next__(self): pass

Dclass MyIter: def iter(self): return self

Step-by-Step Solution

Solution:

Step 1: Check required methods for iterator
An iterator class must have __iter__ returning self and __next__ to get next item.
Step 2: Match methods with options
class MyIter: def __iter__(self): return self def __next__(self): pass correctly defines both __iter__ and __next__ methods.
Final Answer:
Defines both __iter__ and __next__ methods -> Option C
Quick Check:
Iterator class needs __iter__ and __next__ [OK]

Quick Trick: Iterator class must have __iter__ and __next__ methods [OK]
