Challenge 16: Grouping Data into CSV Files Level: Easy Description: You were asked to split a single sales CSV file into smaller ones based on groups, named according to the group names. As an example, if the original file had the following data: Sales Group 100 b 200 a 300 a You would generate two files: one named Group_a, and one named Group_b. They would have the following structure: Sales Group 200 a 300 a and Sales Group 100 b Your solution to this task should be generic — that is, it should work for any number of groups, and the names of the groups should not matter.
