Practical Data Wrangling

File system setup

To follow along with the exercises, you should create a project folder called ch4 to contain all of the code and data. There are a number of different programs, input datasets, and output datasets involved in the projects and exercises in this chapter. To keep things organized, I've created an additional folder to contain the code for the chapter. I've also fragmented the data folder to separate the input data from the output data. Lastly, I've created a folder to store my notes on the file structure and contents. The following is the file structure that I will be using:

ch4/-->code/---->csv_intro.py---->pandas_intro.py---->json_to_csv.py---->xml_to_json.py-->data/---->input_data/------>scf_extract.json------>roads_by_country.csv ...
