Convert Sets Python Program Example: Created by Joseph C. Richardson

Convert Sets.py

# Create four packed sets, then convert them into packed and sorted, extended lists.
# Check to see if their values are all sorted and reversed. After that, reconvert the
# 'convert1' list back into a very long extended unsorted, unpacked set. Type and
# execute/run the program example below and see what happens.
