How to convert a dictionary to Pandas df?-CodePudding

I have tried this following code to get live data from an api.

feed_opened = False

def event_handler_feed_update(tick_data):  
    print(tick_data)  
    # print("feed event: {0}".format(time.strftime('%d-%m-%Y %H:%M:%S'))   str(tick_data))
    # dctmessage = {k:[v] for k,v in tick_data.items()}
    df1 = pd.DataFrame.from_dict(tick_data)
    # df1.to_csv("E:/Python/tickdata.csv",mode="a", index=False)
    print (df1)

def open_callback():
    global feed_opened
    feed_opened = True

api.start_websocket(subscribe_callback=event_handler_feed_update, socket_open_callback=open_callback)

while(feed_opened==False):
    pass

api.subscribe("CDS|5316", feed_type="d")

I have tried to convert tick_data to pandas dataframe. But getting the following output....

ERROR:websocket:error from callback <bound method NorenApi.__on_data_callback of <api_helper.ShoonyaApiPy object at 0x00000000056FCD00>>: If using all scalar values, you must pass an index

How can I make proper dataframe?

CodePudding user response：

This should do the trick:

pd.DataFrame.from_records([tick_data])

CodePudding user response：

Let's assume you have a dictionary like: d = {'Saha':1,'Sourav':2,'family': 3} then, we have to extract dictionary items like this dict_items = d.items() Now convert the dict_items into an list item_list = list(dict_items) Finally,Convert the list into a dataframe using pandas df = pd.DataFrame(item_list)
