Loops 4

This is a follow up to Loops 3

One of your collaborators has posted a comma-delimited text file online for you to analyze. The file contains dimensions of a series of shrubs (ShrubID, Length, Width, Height) and they need you to determine their volumes. You could do this using a spreadsheet, but the project that you are working on is going to be generating lots of these files so you decide to write a program to automate the process.

Use this function to download the data and then use a for loop to calculate the volumes and return a list of lists where the first item in each sublist contains the ShrubID and the second item contains the volume. There should be one sublist for each ShrubID. Once you have created this list, use another for loop to print out each combination of ShrubID and volume on it’s own line in a string like ‘The volume of shrub a1 is 22.5.’

Download the data (note that it has a header this time), use np.loadtxt() to import it into Python, and then use a for loop to calculate the volumes and return a list of lists where the first item in each sublist contains the ShrubID and the second item contains the volume. There should be one sublist for each ShrubID. Once you have created this list, use another for loop to print out each combination of ShrubID and volume on it’s own line in a string like ‘The volume of shrub a1 is 22.5.’
