As machine learning practitioners, we need to collect stock price data for regression analysis and time series analysis. We can easily download it from Yahoo Finance. But imagine if we want to create an application where we can analyze the real-time stock prices, we need to collect the latest dataset instead of using the downloaded dataset. So if you want to learn how to get the stock price data between any time interval by using the Python programming language, this article is for you. In this article, I will take you through how to get stock price data using Python.
Get Stock Price Data using Python
Yahoo Finance is one of the most popular websites to collect stock price data. You need to visit the website, enter the company’s name or stock symbol, and you can easily download the dataset. But if you want to get the latest dataset every time you are running your code, you need to use the yfinance API. yfinance is an API provided by Yahoo Finance to collect the latest stock price data.
To use this API, you need to install it by using the pip command in your terminal or command prompt as mentioned below:
- pip install yfinance
I hope you have easily installed this API. Now below is how you can get the latest stock price data using Python:
import pandas as pd
import yfinance as yf
import datetime
from datetime import date, timedelta
today = date.today()
d1 = today.strftime("%Y-%m-%d")
end_date = d1
d2 = date.today() - timedelta(days=360)
d2 = d2.strftime("%Y-%m-%d")
start_date = d2
data = yf.download('AAPL',
start=start_date,
end=end_date,
progress=False)
print(data.head())Open High ... Adj Close Volume Date ... 2020-12-28 133.990005 137.339996 ... 135.852509 124486200 2020-12-29 138.050003 138.789993 ... 134.043640 121047300 2020-12-30 135.580002 135.990005 ... 132.900681 96452100 2020-12-31 134.080002 134.740005 ... 131.876999 99116600 2021-01-04 133.520004 133.610001 ... 128.617111 143301900 [5 rows x 6 columns]
The above code will collect the stock price data from today to the last 360 days. In this dataset, Date is not a column, it’s the index of this dataset. To use this data for any data science task, we need to convert this index into a column. Below is how you can do that:
data["Date"] = data.index
data = data[["Date", "Open", "High",
"Low", "Close", "Adj Close", "Volume"]]
data.reset_index(drop=True, inplace=True)
print(data.head())Date Open High ... Close Adj Close Volume 0 2020-12-28 133.990005 137.339996 ... 136.690002 135.852524 124486200 1 2020-12-29 138.050003 138.789993 ... 134.869995 134.043640 121047300 2 2020-12-30 135.580002 135.990005 ... 133.720001 132.900696 96452100 3 2020-12-31 134.080002 134.740005 ... 132.690002 131.876999 99116600 4 2021-01-04 133.520004 133.610001 ... 129.410004 128.617096 143301900 [5 rows x 7 columns]
So as you can see, the final dataset is just like the dataset that we download from Yahoo Finance. This is how we can get stock price data using Python.
Summary
So this is how you can collect the latest stock price dataset between any time interval, using the Python programming language. If you want to get the latest dataset every time you are running your code, you need to use the yfinance API. yfinance is an API provided by Yahoo Finance to collect the latest stock price data.
