Question

Write a program that asks the user for a student name and asks for grades until the user enters a non-number input, it should then ask if the user wants to enter another student, and keep doing the process until the user stops adding students.

The student’s must be stored in a dictionary with their names as the keys and grades in a list.

The program should then iterate over the dictionary elements producing the min, max, and mean of their grades.

Example Execution:
Enter a student name: "MaryJo"
Enter a Grade for MaryJo: 88
Enter a Grade for MaryJo: 71
Enter a Grade for MaryJo: 90
Enter a Grade for MaryJo: done
Do you want to add another student: yes
Enter a student name: "Jim"
Enter a Grade for Jim: 85
Enter a Grade for Jim: 89
Enter a Grade for Jim: no
Do you want to add another student: No
Student Stats: MaryJo (71 -90): 83 Jim (85 -89): 87
  

Answer 1

Explanation::

• Code in python is given below
• Screenshot of code is also provided
• Output is given at the end of the code

Code in PYTHON::

import statistics
'''
First we declare an dictionary named studentData
Where key will be name and value will be list of grades
'''
studentGrade = {}
'''
Using while loop we continue asking if user wants to
add student or no
'''
while True:
    name = input("Enter a student name:")
    name = name.strip('"')
    if name not in studentGrade.keys():
        studentGrade[name]=[]
    while True:
        print('Enter a Grade for ',name,':',end='',sep='')
        grade = input()
        if grade.isdigit():
            studentGrade[name].append(int(grade))
        else:
            break
    add = input("Do you want to add another student:").lower()
    if add=='no':
        break
print('Student stats: ',end='',sep='')
for name, grade in studentGrade.items():
    minimum = min(grade)
    maximum = max(grade)
    meanValue = statistics.mean(grade)
    print(name,' (',minimum,'-',maximum,'):',meanValue,' ',end='',sep='')
print()

OUTPUT:
