Download site with selected CGI input

So I have this script:
http://ift.tt/1JrcpWF
How do I download for example, file which has input 1880: http://ift.tt/1SUjWig from this site
They are all cgi files and when I enter http://ift.tt/Y9onHf, it gaves me output for 2013. But I checked the code of the sites and there is input for year and number of entries. So how do I select the entry I need using Python?
