Question

In python, Implement a function studentID() which allows the user to enter the 7-digit student ID. The program will keep prompting the user for a last name and first name. If the student does not have a student ID on record, the program will then ask for the student ID, and store that information. If the student already has a student ID, the program will display it, and ask for confirmation whether a new studentID should be assigned (and, if so allows the new studentID to be entered). When the user hits the return key, the program prints a report listing all students with their studentID. Your report does not have to be in alphabetical order, however, if you do want to make it alphabetical, you can use sorted on the keys of your dictionary.

'''
Python version : 3.6
Python program to input and store the student name and id
and once the user has finished entering the names and ids, display
the report containing the student names and ids

# function to input and return the student id from user
def studentID():
  
   id = input('Enter the student ID : ')
   return id
  
# main function  
def main():
   # create a dictionary of students where keys are student first and last name and values are student id
   students = {}
  
   # loop that continues till the user wants
   while True:
       # input the first and last name from user
       name = input('Enter lastname and firstname (input <empty string> to quit) : ')
       # check if user wants to quit
       if len(name) == 0:
           break
       # check if name is already present in dictionary  
       if name in students:
           # if present, ask user if they want to generate a new studentID
           print('Student ID for %s is %s '%(name, students[name]))
           choice = input('Do you want to generate a new student ID (y/n) ? ')
          
           # input a new studentID if the user wants
           if choice.upper() == 'Y':
              
               id = studentID()
               # update the studentID in dictionary
               students[name] = id
              
       else: # if name is not present
           id = studentID() # input the studentID
           # add the student name and id in dictionary
           students[name] = id

   # after loop ends, display the student names and studentID  
   print('%-20s%-15s' %('Name','Student ID'))  
   for name in students:
       print('%-20s%-15s' %(name,students[name]))

# call the main function      
main()      
#end of program
