将python中列表的字符串表示形式转换为列表对象
问题描述：
我有一些格式的数据
[[prod149090160, prod146340131, prod160860042, prod147040186, prod147860348, prod157590283, prod153940219, prod162460011, prod160410115, prod157370014], [prod162290002, prod151790213, prod159380278, prod154180602, prod160020244, prod161410007, prod155540059, prod152810207, prod152870263, prod159300061], [prod156900051, prod157590288, prod153540027, prod162940222, prod160330181, prod162680033, prod155370061, prod156970034, prod159310027, prod159410165]]
这是字符串格式的列表列表.有没有简单的方法可以将其转换为内置的python列表类型.
This is a list of list in string format. Is there any simple way to convert this into an in-built python list type.

或 PyYAML :>
>>> import yaml
>>> s = '[[prod149090160, prod146340131, prod160860042, prod147040186, prod147860348, prod157590283, prod153940219, prod162460011, prod160410115, prod157370014], [prod162290002, prod151790213, prod159380278, prod154180602, prod160020244, prod161410007, prod155540059, prod152810207, prod152870263, prod159300061], [prod156900051, prod157590288, prod153540027, prod162940222, prod160330181, prod162680033, prod155370061, prod156970034, prod159310027, prod159410165]]'
>>> yaml.load(s)
