Python project – realtime stock price

python web scraping stock price

About the Projects

Fetch the current share price of multiple companies​ using Python web scraping

This project describes a Python code, which fetches the current stock price for multiple listed companies. This script first reads the excel sheet to get the list of all companies for which CMP (Current Market Price) has to be calculated and then fire up the browser to open a website which has this information. The automation script enters the name of each stock, one by one, in the search bar which in turn load the page with particular information, from which the CMP is scraped and stored.

This continues until the lists items from the excel sheet get over. Parallelly, scripts also keep on calculating the total profit/loss for each share by comparing it against the Invested price and number of shares. In the end, profit and (or) loss is calculated for each share
and the information is written back to the excel sheet. Excel sheet does further calculation to build up the bar graph for representing the data in the best possible way. Look at the video to get complete information.

  1. Can you explain this line in a little more detail?
    print (“{:>23} -> CMP {:[{:>8.2f}] %P/L -> {:>6.2f}%”.format(c_list[i],s_v.text, diff, per_diff))

    1. Hello Anonymous,
      This is string formatting that has been done to align the results in a specific manner. For example
      :>8.2f means align towards the right side, to 8 spaces and up to 2decimal points of floating value.

  2. File “c:\Users\user\Desktop\my code\scrap.py”, line 53, in
    diff = (avg_val[i] – float(s_v.text))* qnty_list[i]
    ValueError: could not convert string to float:
    this is the error am getting tried many times plz check and do needful

  3. I am getting this error…

    ModuleNotFoundError Traceback (most recent call last)

    1. Hello Tushar,
      It seems like you have not installed selenium library (or package) in your system. Please do so and have the correct version of chrome webdriver. You will be good to go.

  4. Hello Tushar,

    I worked on your example which is pretty interesting, but unfortunately I got some errors and I’m not able to fix them.
    Maybe it’s caused by different versions of python or lib’s?
    Hope you can gibe me some advice?
