There are several ways to feed stock market data into Python. Here are a few common methods:

  1. Web scraping: You can use web scraping libraries like BeautifulSoup or Scrapy to extract data from finance websites or financial news platforms. These websites often provide data on stock prices, volumes, and other related information. However, please note that you should familiarize yourself with the website's terms of service and ensure that you are legally allowed to scrape their data.
  2. APIs: Many financial data providers offer APIs (Application Programming Interfaces) that allow you to programmatically access their data. Popular options include Alpha Vantage, Yahoo Finance API, or Google Finance API. These APIs usually provide a wealth of historical and real-time market data that can be easily integrated into your Python code.
  3. Python libraries: There are Python libraries specifically designed for accessing and working with financial data. For example, the pandas_datareader library provides a simple way to retrieve financial data from various sources, including Yahoo Finance. You can install it using pip: pip install pandas_datareader.

Here's an example of using pandas_datareader to fetch stock market data:

import pandas_datareader as pdr

# Fetch stock data for a specific company and date range
data = pdr.get_data_yahoo('AAPL', start='2020-01-01', end='2020-12-31')

# Print the retrieved data

This code uses the Yahoo Finance API to fetch historical stock data for Apple (AAPL) between January 1, 2020, and December 31, 2020.

Remember to explore each data source's documentation to understand the available data and their APIs or scraping rules.
