In this session, Angie uses the code (
https://github.com/rbavery/ITEP_tutorials/tree/master/data/PINTempData) from the 5/5/20 call to:
1. upload a csv file
2. handle extra/unnecessary rows and columns
3. rename columns
4. filter the data to include only certain dates
She also demonstrates how to make a loop that will automatically:
1. perform all of those tasks on
each file in a directory
2. save the filtered data to a csv file in a
separate directory
