Hi, I need help with a program I am working on. This is the question?

Question

How would I write a Python program that inputs a string of characters which represent a vanity telephone number, e.g., 800-MYPYTHON, and prints the all numeric equivalent, 800-69798466. You should implement this using a loop construct to process each character from left to right. Build a new string that is the all numeric equivalent and then print the string.

Answer 1

phoneNumber = "800-MYPYTHON"

newNumber = ""

for char in phoneNumber:

if(char == "A" or char == "B" or char == "C"):

newNumber += "2"

elif(char == "D" or char == "E" or char == "F"):

newNumber += "3"

elif(char == "G" or char == "H" or char == "I"):

newNumber += "4"

elif(char == "J" or char == "K" or char == "L"):

newNumber += "5"

elif(char == "M" or char == "N" or char == "O"):

newNumber += "6"

elif(char == "P" or char == "Q" or char == "R" or char == "S"):

newNumber += "7"

elif(char == "T" or char == "U" or char == "V"):

newNumber += "8"

elif(char == "W" or char == "X" or char == "Y" or char == "Z"):

newNumber += "9"

else:

newNumber += char

print(newNumber)
