What would you like to do?
Python code test - CARTO

Build the following and make it run as fast as you possibly can using Python 3 (vanilla). The faster it runs, the more you will impress us!

Your program should:

  1. Download this 2.2GB file: (keep in mind, the file could get much bigger in the future)
  2. Count the lines in the file
  3. Calculate the average value of the tip_amount field.

All of that in the most efficient way you can come up with.

So, we'd do:

$ time python
x.00s user x.00s system 81% cpu x.000 total

That's it. Make it fly! Oh, and please do tell us why you did it that way! A quick reasoning about your decisions is always appreciated.
