Answer:

Explanation:

# keys() will be assignmentects1, assignmentect2 etc

# values() will be the marks in each assignmentect like 56, 79 etc

AndrewMarks = { 'assignment1': 56,

'assignment2': 79,

'assignment3': 90,

'assignment4': 22,

'assignment5': 50 }

ColinMarks = { 'assignment1': 88,

'assignment2': 62,

'assignment3': 68,

'assignment4': 75,

'assignment5': 78 }

AlanMarks = { 'assignment1': 95,

'assignment2': 88,

'assignment3': 92,

'assignment4': 85,

'assignment5': 85 }

MaryMarks = { 'assignment1': 76,

'assignment2': 88,

'assignment3': 85,

'assignment4': 82,

'assignment5': 90 }

TriciaMarks = { 'assignment1': 99,

'assignment2': 92,

'assignment3': 95,

'assignment4': 89,

'assignment5': 99 }

# Calculate total of each student and store them in the new dictionary

AndrewTot = AndrewMarks['assignment1'] + AndrewMarks['assignment2'] + AndrewMarks['assignment3'] + AndrewMarks['assignment4'] + AndrewMarks['assignment5']

ColinTot = ColinMarks['assignment1'] + ColinMarks['assignment2'] + ColinMarks['assignment3'] + ColinMarks['assignment4'] + ColinMarks['assignment5']

AlanTot = AlanMarks['assignment1'] + AlanMarks['assignment2'] + AlanMarks['assignment3'] + AlanMarks['assignment4'] + AlanMarks['assignment5']

MaryTot = MaryMarks['assignment1'] + MaryMarks['assignment2'] + MaryMarks['assignment3'] + MaryMarks['assignment4'] + MaryMarks['assignment5']

TriciaTot = TriciaMarks['assignment1'] + TriciaMarks['assignment2'] + TriciaMarks['assignment3'] + TriciaMarks['assignment4'] + TriciaMarks['assignment5']

TotalMarks = { 'Andrew': AndrewTot,

'Colin' : ColinTot,

'Alan' : AlanTot,

'Mary' : MaryTot,

'Tricia': TriciaTot}

StudentHighestTotal = max(TotalMarks)

HighestTotalMarks = TotalMarks[max(TotalMarks)]

Averages = { 'assignment1Average': (AndrewMarks['assignment1'] + ColinMarks['assignment1'] + AlanMarks['assignment1'] + MaryMarks['assignment1'] + TriciaMarks['assignment1'] ) / 5 ,

'assignment2Average': (AndrewMarks['assignment2'] + ColinMarks['assignment2'] + AlanMarks['assignment2'] + MaryMarks['assignment2'] + TriciaMarks['assignment2'] ) / 5 ,

'assignment3Average': (AndrewMarks['assignment3'] + ColinMarks['assignment3'] + AlanMarks['assignment3'] + MaryMarks['assignment3'] + TriciaMarks['assignment3'] ) / 5 ,

'assignment4Average': (AndrewMarks['assignment4'] + ColinMarks['assignment4'] + AlanMarks['assignment4'] + MaryMarks['assignment4'] + TriciaMarks['assignment4'] ) / 5 ,

'assignment5Average': (AndrewMarks['assignment5'] + ColinMarks['assignment5'] + AlanMarks['assignment5'] + MaryMarks['assignment4'] + TriciaMarks['assignment5'] ) / 5

}
