yield from 语法

def flatten(nested):
   for sublist in nested:
       yield from sublist

nested = [[1, 2], [3, 4]]
print(list(flatten(nested)))  # [1, 2, 3, 4]

协程通信

def coroutine():
   while True:
       value = yield
       print(f"收到: {value}")

coro = coroutine()
next(coro)  # 启动协程
coro.send("Hello")
