I am trying to use Python 2.7 to open a web browser and download and save a linked kml file.

The website is:
rmgsc.cr.usgs.g ov/outgoing/GeoMAC/ActiveFirePerim eters.kml

When I run the code below, a new kml file appears to be saved on my drive, however it does not bring over the entire file. Instead of 154MB, it brings over a file that is only 17 bytes.

I can either go to the website (rmgsc.cr.usgs. gov/outgoing/GeoMAC/)...
