一个python生成器的使用

def myegg(retlist):
    for i in retlist:
        rec = yield i

mydict = [
    {"name":"厉智","age":},
    {"name":"陈培昌","age":},
    {"name": "程劲", "age": },
]

b = myegg(mydict)
obj = b.__next__()
print("喜欢{}，芳龄{}".format(obj['name'],obj['age']))
obj2 = b.__next__()
print("喜欢{}，芳龄{}".format(obj2['name'],obj2['age']))
obj3 = b.__next__()
print("喜欢{}，芳龄{}".format(obj3['name'],obj3['age']))

打印结果:

喜欢厉智，芳龄31
喜欢陈培昌，芳龄21
喜欢程劲，芳龄20

或者循环遍历访问，因为生成器也是可迭代的
b = myegg(mydict)
for i in b:
    print("喜欢{}，芳龄{}".format(i['name'], i['age']))
