Write a program that can read the students records from the file “scores.dat”. This program will find the maximum and the minimum student scores. The first line in the file is a header. Each line (starting from the second line) contains the records of one student separated by spaces. These records are: the last name, the first, name, the ID, and the score.
# ETHAN PLYMALE
infile = open(scores.dat, 'r')
# Finding the maximum
and now I do not know what to do?
