Example 1 prints out the UNESCO dataset to the terminal window. This is just a simple read of the CSV file and a print to the terminal or console window
Example 2 prints out the UNESCO dataset to another CSV file. We see in the example where we only choose specific columns from the input file which are then written to a tab separated output file
Example 3 makes a simple subset of the large UNESCO dataset. We take a subset of the data on the 'category' which sites are classified by. The new subset is written to a CSV output file
Example 4 uses the pyton data structured called a dictionary to count items in a dataset
