python将字符串类型list转换成list
python读取了一个list是字符串形式的'[11.23,23.34]',想转换成list类型:
import ast str_list = "[11.23,23.34]" list_list = ast.literal_eval(str_list) print(type(list_list))
得到结果为:
<class 'list'>
方式二:
import json str_list = "[11.23,23.34]" list_list = json.loads(str_list) print(type(list_list))
得到结果为:
<class 'list'>
