Earlier this month, Google introduced the new Google Search Console API and it was expected that legacy methods to export your data from the Google Search Console would go away, eventually.
Well, Google's John Mueller announced on Google+ that the python script they released back in December 2011 will be sunsetted on October 20, 2015.
John Mueller said:
It's been a while since the introduction of the Python script to download search query data from Webmaster Tools in 2011. With the new Search Analytics API & the Client Login API deprecated, it's now time to wind down support for the CSV download scripts.We'll be turning off support for the scripted download of the CSV files on October 20, 2015.
This should come as no surprise, as there are more efficient methods to now get this data.
Obviously, if you are using this python script, you will need to look into upgrading into the new API.
