What is generator in python?

Question

I don't understand generator and what is generator in other languages like Java and c++?

Answer 1

Python generator : Generators functions allow you to declare a function that behaves like an iterator, i.e. it can be used in a for loop.

Answer 2

I read this definition but it's not clear for me. Are there any other explanation?

Answer 3

generator basically allows you to return a function's output infinite times using for and yield instead of return word where you just exit the function by destroying all the temporary values created in between
