Answer:
The Python code is given below with appropriate comments
Explanation:
# FIXME: Create add_grade function
def add_grade(student_grades):
print('Entering grade. \n')
name, grade = input(grade_prompt).split()
student_grades[name] = grade
# FIXME: Create delete_name function
def delete_name(student_grades):
print('Deleting grade.\n')
name = input(delete_prompt)
del student_grades[name]
# FIXME: Create print_grades function
def print_grades(student_grades):
print('Printing grades.\n')
for name, grade in student_grades.items():
print(name, 'has a', grade)
student_grades = {} # Create an empty dict
grade_prompt = "Enter name and grade (Ex. 'Bob A+'):\n"
delete_prompt = "Enter name to delete:\n"
menu_prompt = ("1. Add/modify student grade\n"
"2. Delete student grade\n"
"3. Print student grades\n"
"4. Quit\n\n")
command = input(menu_prompt).lower().strip()
while command != '4': # Exit when user enters '4'
if command == '1':
add_grade(student_grades)
elif command == '2':
# FIXME: Only call delete_name() here
delete_name(student_grades)
elif command == '3':
# FIXME: Only call print_grades() here
print_grades(student_grades)
else:
print('Unrecognized command.\n')
command = input().lower().strip()
