+This repository contains Python code for reading agricultural CO2 emissions data.
+
+### Changes ###
+- Implemented "get_column()" in "my_utils.py" to read a file line-by-line and return values from a selected column
+- Updated "get_column()" so that "result_column" defauls to column 1
+- Updated "print_fires.py" to print forest fire emissions for the United States
+- Added "run.sh" to run "print_fires.py"
+
+### Running the Script ###
+
+Run the script with: 
+
+bash run.sh
+
+The data file "Agrofood_co2_emission.csv" must be present in the repo directory but do not commit it to Git.
