#定義一個產生器，形式與函數相同，區別在於yield關鍵字，它其實類似於returndef easyYield():    yield 1    yield 2#將產生器執行個體化一個對象，綁定在變數身上，通過next取得yield的內容a = easyYield()print(next(a))print(next(a))#第二個執行個體，升級版的產生器def libs():    a,b=0,1    while True:        a,b = b,a+b        yield afor each in libs():    if each > 100:        break    print(each,end=",")print("-----------------------------------------------------")#列表推導式a = [i for i in range(100) if not(i % 2) and i % 3]print(a)#字典推導式b = {i:i%2==0 for i in range(10)}print(b)#集合推導式c = {i for i in [1,2,1,3,12,4,2,2,4,5,3,5]}print(c)#產生器推導式d = (i for i in range(10))print(next(d))print(next(d))
