interface class.This is done to achieve a concept called "normalization".The so-called normalization idea is that as long as the class is implemented through the same interface class (abstract class), the objects produced by these classes are the same as the methods used.To be more understandable, it is that we no longer need to be concerned about which class the object is generated from, as long as we know what these objects are capable of.For example: We have a car interface, which defines al

we print out every element of generator?If you want to print out one, you can next() get the next return value for generator by using a function:def fib (max): = 0, 0, 1 while n Max: print(b) = B, A + b = n + 1 return'done'In other words, the above functions and generator are only a step away. To turn a fib function into a generator, you just need to print(b) change yield b it, and that's another way to define generator. If a function definition contains a
