Question :

Write a program to take in a telephone number that uses letters instead of numbers, such as 1-800-CALL-ATT. The program should use a function called "convertLetter () " to convert each letter to the corresponding number.

For this exercise, assume the following:

ABC

=

2

DEF

=

3

GHI

=

4

JKL

=

5

ICO

=

6

PQRS

=

7

TIN

=

8

WXYZ

=

9

You may want to check if the input is a digit (0-9) or not. To do this, you can use the isdigit 0 function. It will return True if the string passed in is a digit, or False if it is not a digit. For example, this returns True: var = "5"

myBool = var.isdigit()
