一篇文章带你了解python迭代器和生成器

dict1 = {
    'name':'laowang',
    'age':18,
    'high':180
}
iterator = dict1.__iter__()
while True:
    try:
        res = iterator.__next__()
    except:
        break
    else:
        print(res,dict1[res]

list1 = [i for i in range(1,10)]
# 结果
[1, 2, 3, 4, 5, 6, 7, 8, 9]

list1 = (i for i in range(1,10))
# 结果
<generator object <genexpr> at 0x7fa491ea3410>
# generator 生成器
#生成器函数
def func1():
    for i in range(1,10):
        yield i
res = func1() #生成器对象
for i in res:
    print(i)
