如何将这个json对象转换为pandas数据框？

Question

I have a csv file that I turn into a json so that I can turn it into a panda data-frame.

Here is my code,

def create_png():

    f = open('sticks.csv', 'r')
    reader = csv.DictReader( f, fieldnames = ("xstk", "stk") )
    out = json.dumps( [row for row in reader ] )
    print out

    df = DataFrame([
        #TODO
    ])

The line 'print out' prints out "[{"xstk": "1", "stk": "0"}, {"xstk": "0", "stk": "1"}, {"xstk": "1", "stk": "0"}]"

So what can I put into #TODO to make the code run and turn this into a simple two column dataframe? I have looked at Create pandas dataframe from json objects but it is a complicated example.

Answer 1

Simply read the string of the json in directly to read_json :

In [11]: pd.read_json('[{"xstk": "1", "stk": "0"}, {"xstk": "0", "stk": "1"}, {"xstk": "1", "stk": "0"}]')
Out[11]:
   stk  xstk
0    0     1
1    1     0
2    0     1

However, if you already have a csv you should really read it in directly using read_csv :

df = pd.read_csv('sticks.csv', names=["xstk", "stk"])
