Simple loop error
Dr. Larson,
I am working the example below in the Anaconda env using the class Jupyter notebook, and I have encountered the following error which says int_val is not defined. I have checked the code several times and can only conclude that this variable does not exist in the "DataMining" list (?).
I would certainly appreciate your thoughts,
Luke Pierce
