Software programs called Spiders
When you are on Google and you decide to do a search, you are not searching the web pages. What you are doing is actually searching Google’s index of the web page. This is done with programs called spiders. They start off by fetching a few web pages, then follow links to those pages and collect all the pages they point to; and follow all the links, and then again fetch the pages they link to, and so forth. This is done until we have indexed a huge chunk of the web.
Answer:
x = 1 ; y = 1
Explanation:
The newly created AVG column will contain the mean value of all 6 columns(P2010, P2011, P2012, P2013, 2014 and P2015) this means that we are taking the mean across the columns as our AVG column have the same length as the initial lengtb of the data Frame as all a values in each index are averaged to create the new column. To achieve this the value 1 will be passed to the axis argument in the apply method.
To drop the previous 6 columns, we se the axis argument set to 1, this will delete the columns passed to the drop method.
Hence, both x and y values of the axis argument will take the value 1.
