Iterator, yield expression, generator, coroutine, and iteratorcoroutine in Python Every time I look at the code written by others, I have yield. I feel like a super geek. Today I will spend some time organizing it. In order: 1. iterator Iterator is

Yield command. You can pause a function and return intermediate results. The function that uses this command will save the execution environment and restore it if necessary. The generator is more powerful and complex than the iterator, so it takes
