python 遍历list元素是dict的错误：list indices must be integers or slices, not dict

list_data = [{"sku_id":"800001183","launch_time":"2021-05-29 00:00:00"},
{"sku_id":"800001182","launch_time":"2021-05-29 00:00:00"},
{"sku_id":"800001172","launch_time":"2021-05-29 00:00:00"},
{"sku_id":"800001171","launch_time":"2021-05-29 00:00:00"},
{"sku_id":"800001181","launch_time":"2021-05-24 00:00:00"},
{"sku_id":"800001180","launch_time":"2021-05-24 00:00:00"},
{"sku_id":"800001170","launch_time":"2021-05-24 00:00:00"},
{"sku_id":"800001183","launch_time":"2021-05-29 00:00:00"}]

 

在python里遍历list的方法是:

for i in list_data:
    print(list_data[i])

但是针对元素是dict的列表这么写会报错：

list indices must be integers or slices, not dict

因为这个时候i并不是数字0,1,2......而是第一个dict，第二个dict

所以要这么遍历：

for i in list_data:
    print(i['sku_id'])
    print(i['launch_time'])
