# Python3 program which calculates final mark based on previous and potential future marks.
# How to use this program:
# - modify "previous_marks" list (line 18)
# - run the program
# If the program fails to run because of missing libraries, you can run the following command:
# python3 -m pip install matplotlib tk numpy
