title: downloading csv files from a specific site using python
body: <p>Goal: want to automatize the download of various .csv files from <a href="https://wyniki.tge.pl/en/wyniki/archiwum/2/?date_to=2018-03-21&amp;date_from=2018-02-19&amp;data_scope=contract&amp;market=rtee&amp;data_period=3" rel="nofollow noreferrer">https://wyniki.tge.pl/en/wyniki/archiwum/2/?date_to=2018-03-21&amp;date_from=2018-02-19&amp;data_scope=contract&amp;market=rtee&amp;data_period=3</a> using Python (this is not the main issue though)</p>
  
  <p>Specifics: in particular, I am trying to download the csv file for the "Settlement price" and "BASE Year"</p>
  
  <p>Problem: when I see the source code for this web page.I see the references to the "Upload" button, but I don't see refences for the csv file(Tbf I am not very good at looking at the source code). As I am using Python (urllib) I need to know the URL of the csv file but don't know how to get it.</p>
  
  <p>This is not a question of Python per se, but about how to find the URL of some .csv that can be downloaded from a web page. Hence, no code is provided.</p>
