convert dict to pandas dataframe

for example:

symbol last_price net_change Open High Low Close
NSE:ACC 2488.9 0 2575 2585.5 2472.2 2555.7

I am trying pd.DataFrame.from_dict(main_dict) but it does not work. please give the best suggestion.

CodePudding user response：

I would first select the necessary data from your dict and then pass that as input to pd.DataFrame()

df_input = [{
    "symbol": symbol,
    "last_price": main_dict.get(symbol).get("last_price"),
    "net_change": main_dict.get(symbol).get("net_change"),
    "open": main_dict.get(symbol).get("ohlc").get("open"),
    "high": main_dict.get(symbol).get("ohlc").get("high"),
    "low": main_dict.get(symbol).get("ohlc").get("low"),
    "close": main_dict.get(symbol).get("ohlc").get("close")
} for symbol in main_dict]

import pandas as pd
df = pd.DataFrame(df_input)
