Overview

Py(A)vanza

Fetch fund data from avanza.se using Python and some web scraping with bs4. The default way is to display the data in the terminal, apply --json for json output.

How does it work?

Provide this script with the fund id (can be found in the url of the fund, example below). The script is scraping the funds page and displays the output.

How is this useful?

You can use this data for your own project, perhaps on a Raspberry Pi with a display?

Installation

We're going to use selenium with chrome driver for this one. So apt install chromium-chromedriver and xvfb.

$ sudo apt install chromium-chromedriver
$ sudo apt install xvfb

Next, clone repo and install requirements (preferably inside a virtualenv of some sort).

$ git clone 
   
    
$ mkvirtualenv pyvanza
$ pip install -r requirements.txt

Grab the fund id from url. In this case the id is 325406.
