# Here is a pastebin link for code: https://pastebin.com/VKWJMxgK

from Student import *

#This function prints out the heading part of the menu

continue
else:
if userChoice < 1 or userChoice > maxValue:
continue
else:
return (userChoice)
def read_solution():
#This function returns a list of solution from file.

try:
file=input("Enter name of the solution file: ")
with open(file) as f:
for val in f.read().split(","):

## You may need to add some helper functions:

  
#def display_result(class_list):
#This function ...
#print()

  
#def display_summary(marks):
#This function ...
#print("Grade Summary:")

def display_menu():
#This function prints out the menu
print("1. Read a Solution")
print("2. Read a ClassList")
print("3. Start Marking")
print("4. Display the Marking Result")
print("5. Display the Marking Summary")
print("6. Quit the program")

def display_separator():
#This function prints out the separator
lines = "-" * 40
print(lines)

solutions = []
studentslist = []
def menu():
display_menu()
display_separator()
option = get_user_input(1,6)
while option != 6:
if option == 1:
display_separator()
read_solution()
elif option == 2:
display_separator()
read_classlist()
elif option == 3:
display_separator()
start_marking(solutions, studentslist)
elif option == 4:
display_separator()
else:
display_separator()
display_separator()
display_menu()
display_separator()
option = get_user_input(1,6)
display_separator()
print("Thank you!")
raise SystemExit
  
def main():
display_separator()
display_intro()
display_separator()
menu()
display_separator()

main()
