Python字符串分割问题

形如[['022302120222'], ['222223111032'], ['301322130302']这样的list如何转换成[['0',
'2','2','3','0',...],['2','2','2','2'....],[...]]

话说今天已经回过你一次了，python 2.7 的

 Str="123dfhgdfh45";
def Split(Str):
    "字符串切割"
    List=[];
    i=0;
    while i<len(Str):
        List.insert(i, Str[i]);
        i+=1;
    return List;
print Split(Str);

res = [list(item) for sublist in ls for item in sublist]
使用列表解析和内置函数才是首选，感觉楼上不是Pythoner

ls = [['022302120222'], ['222223111032'], ['301322130302']]
res = [list(item) for sublist in ls for item in sublist]
楼上厉害
