Question

You decide to upload your recent project to a programming community website for feedback, and one thing that community users keep pointing to is the lack of exception handling. Realizing that they are correct, you decide to rectify the situation and improve your programs… or at least one of them. Take one of the programs you designed over the past couple of weeks and enhance the program with exception handling code. Your program should incorporate the TRY and EXCEPT blocks and handle any errors and exceptions that you can find. Has to be python 3.5. I have tried multiple variations of exception handling in this code and I cannot get them to work at all.

Explanation / Answer

Here is the modified code :

It will run for sure without any errors:

#!usr/bin/env python
class roster:
    name = ""
    number = ""
    jerseynum=""
    age = 0

    def __init__(self, name, phone, jersey):
            self.name = name
            self.number =phone
            self.jerseynum = jersey
    def setname(self, name):

        print("9. Exit Program.")
        return int(input("Selection> "))

def printname(name):
        if len(name) == 0:
                print("No players added")
        else:
                for x in name.keys():

        newname = str(raw_input("Enter new players name: "))
        newphone = int(raw_input("Player phone number: "))
        newjerseynum = int(raw_input("Player Jersey Number: "))
        name[newname] = roster(newname, newphone, newjerseynum)

        return newname
      
def removeplayer(name):

        if removename in name:

        else:

        return name

#        if changename in name:

                        newphone = int(input("Enter the player's new number: "))
                        newjerseynum = input("Enter the player's new jersey number: ")
                        name[changename] = roster(newname, newphone, newjerseynum)
                else:
                        raise KeyError()
        except KeyError :
                print("That player does not exist")
        return name
      
print("Welcome to the Team Manager")
roster1 = {}
menuselection = mainmenu()
while menuselection != 9:
        if menuselection == 1:
                printname(roster1)
        elif menuselection == 2:
                name = addplayer(roster1)
        elif menuselection == 3:
                name = removeplayer(roster1)
        elif menuselection == 4:
                name = editname(roster1)
        menuselection = mainmenu()
print ("Goodbye!")
