You need to obtain the names of the CSV files in your folder. The
os.listdir function or the fnmatch function can obtain these for you.
Then write a loop which iterates over the filenames. Open each and read
it with the csv.reader function.
Collect the values from the fifth column and track the max and min
values. Compare them at the end.
This feels like a homework question: we don’t write code for you because
you will learn little, but we will assist with suggestions and answer
questions if you have partial but not yet working code.
