有沒有辦法從字典中提取數據到csv文件

Question

下面的代碼會將多個股票數據放入字典中。 但我需要將它們放入一個 csv 文件中

代碼：

import pandas as pd
from datetime import datetime as dt
from nsepy import get_history

stocks = ['JSWSTEEL','RELIANCE','AXISBANK','HCLTECH','TECHM']
df = {}
for tickers in stocks:
    df[tickers] = get_history(tickers,dt(2020,1,1),dt(2021,1,1))

Answer 1

使用 pandas 從字典中創建一個 DataFrame，然后使用 pandas.to_csv() 函數，如下所示：

import pandas as pd
from datetime import datetime as dt
from nsepy import get_history

stocks = ['JSWSTEEL','RELIANCE','AXISBANK','HCLTECH','TECHM']
df = {}
for tickers in stocks:
    df[tickers] = get_history(tickers,dt(2020,1,1),dt(2021,1,1))

dataset = pd.DataFrame([df], index=[0])
csv_data = dataset.to_csv("your_file_path.csv")

工作精美！
