Many companies use telephone numbers like 555-GET-Food so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion:A, B, and C = 2D, E, and F = 3G, H, and I = 4J, K, and L = 5M, N, and O = 6P, Q, R, and S = 7T, U, and V = 8W, X, y, and Z = 9Write an application that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD the application should display 555-438-3663.

Answer :

print("Given the following was entered from the keyboard"

                "\n555-GET-FOOD:\n555-438-3663")

phoneNum = input()

newPhoneNumber = ""

for char in phoneNum:

   if char == 'A' or char == 'B' or char == 'C':

       char = '2'

   elif char == 'D' or char == 'E' or char == 'F':

       char = '3'

   elif char == 'G' or char == 'H' or char == 'I':

       char = '4'

   elif char == 'J' or char == 'K' or char == 'L':

       char = '5'

   elif char == 'M' or char == 'N' or char == 'O':

       char = '6'

   elif char == 'P' or char == 'Q' or char == 'R' or char == 'S':

       char = '7'

   elif char == 'T' or char == 'U' or char == 'V':

       char = '8'

   elif char == 'W' or char == 'X' or char == 'Y' or char == 'Z':

       char = '9'

       

   newPhoneNumber = newPhoneNumber + char

print(newPhoneNumber)
