A text file has student data such that each line of text has a student first name (a non-empty alphabetic string) followed by exam scores (non-negative integers) separated by spaces. the number of scores might be different for each student, and each student has at least one score. see studentdata1, student data2, and student data3 in the drive folder homework. define a function student_minmax(filename) that has one parameter, the name of the file that has the student data, and returns a dictionary. the dictionary has the student names as keys and, as values, a list of two scores, the min and max scores for that student. for example, the call student_minmax('studentdata1.txt') will return the dictionary: {'joe': [5, 10], 'sue': [7, 10]}.

def student_minmax(filename):
