In this video, you will learn Generator function in Python.
Generator in Python:
1. Generator is a function that returns an object (iterator) which we can iterate over (one value at a time).
2. A generator-function is defined like a normal function, but whenever it needs to generate a value, it does so with the yield keyword rather than return.
3. If the body of a def contains yield, the function automatically becomes a generator function.
4. Generator functions return a generator object. Generator objects are used either by calling the next method on the generator object or using the generator object in a “for in” loop.
5. "return" statement terminates a function entirely and "yield" statement pauses the function saving all its states and later continues from there on successive calls.
