Question

in python

Write a program that keeps a dictionary in which both keys and values are strings—names of students and their course grades. Prompt the user of the program to add or remove students, to modify grades, or to print all grades. The printout should be sorted by name and formatted like this: Carl: B- Joe: C Sarah: A Francine: A

Answer 1

dict = {}
inp=raw_input("Select option \n 1 for adding. \n 2 for removing. \n 3 for modifying. \n 4 for printing. \n 5 for exit. \n")
while (inp != '5'):
   if inp =='1' :
       name=raw_input("Enter the name of student: ")
       grade=raw_input("Enter its grade: ")
       dict[name]=grade
   elif inp =='2' :
       name=raw_input("Enter the name: ")
       try:
           dict.pop(name)
       except :
           print("Not found. ")
   elif inp =='3' :
       name=raw_input("Enter the name of student: ")
       grade=raw_input("Enter grade: ")
       dict[name]=grade
   elif inp =='4' :
       for x in sorted(dict):
           txt="{} : {} "
           print(txt.format(x,dict[x]))
   else :
       print("You have entered wrong number")
   inp=raw_input("Select option \n 1 for adding. \n 2 for removing. \n 3 for modifying. \n 4 for printing. \n 5 for exit. \n")
