TEA [102]
Its important to have user accounts so you can save data and maybe log in and out of a device/cmp to another one. The purpose of the user account is to help save your stuff and personalize your device. The features are more data storage to add up, and ability to make more accounts for others so each of you can personally have their own account and save their own data on their own. Administrator accounts are the highest and have the most power of all, they are in charge of everything, especially giving permission to apps you may have downloaded and removing system apps. Users rights are the tasks specific users can do to make sure no user has too much power or less so to speak and it means what you are able/not able to do as well.

elena-s [515]

Answer:

Explanation:

The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.

def in_values():

   num_list = []

   while True:

       try:

           num = input("Input non-zero floating point: ")

           num = int(num)

           if num == 0:

               break

           else:

               num_list.append(num)

       except ValueError:

           print("No valid integer! Please try again ...")

           try:

               num = input("Input non-zero floating point: ")

               num = int(num)

               break

           except ValueError:

               break

   sum = 0

   for number in num_list:

       sum += number

   return sum
