Hello,
I'm using Dictreader to store a CSV with column headers in a container. I didn't have any issues bringing the CSV into the
container, but I can't seem to grasp how to access the nested keys and values. From what I can tell, the 1st column is my primary key, but then subsequent column headers are also keys with values. I'm confused on how to retrieve a value from one of the sub-keys. For example, my primary key which I specified as a fieldname is called "Cars". I need to first find "Cars", then a second associated column (also a key)called "Model"...and then the associated value of "Model". Hopefully, that makes sense: Cars > Model > Value of Model.
