我有一个名为js的json格式的字符串列表。

但是当我做的时候

pd.read_json(js)

我收到错误说

  

TypeError Traceback（最近一次调用最后一次）    in（）   ----＆GT; 1 pd.read_json（js）

     

// anaconda / lib / python2.7 / site-packages / pandas / io / json.pyc in＆gt; read_json（path_or_buf，orient，typ，dtype，convert_axes，convert_dates，＆gt; keep_default_dates，numpy，precise_float，date_unit ）      209 obj = FrameParser（json，orient，dtype，convert_axes，＆gt; convert_dates，      210 keep_default_dates，numpy，precise_float，    - ＆GT; 211 date_unit）.parse（）      212      213如果typ =='series'或obj是None：

TypeError：预期的字符串或Unicode

我通过

来实现它 
df = pd.DataFrame()

for j in js:

    data = pd.read_json(j, typ='list')

    df=df.append(data,ignore_index=True)

永远执行。

我的问题是，如果我被允许一次读取一个列表并将其附加到空数据帧，为什么我只能读取整个列表而不会出现错误？有什么方法可以解决这个问题吗？感谢。
