1. 使用生成器实现斐波那契
注意： 1. 使用yield
2. 代码
def create_num(count):
current_count = 0
a, b = 0, 1
while current_count < count:
yield a
a, b = b, a + b
current_count += 1
obj = create_num(20)
# res = next(obj)
# print(obj)
for num in obj:
print(num)
# while True:
# try:
# res = next(obj)
# print(res)
# except Exception as e:
# break
