Please help me break down the answer for this question *in Python*: -how do you get the 'FLOWERS' portion to work in python etc.?

For this lab, write a program that prompts the user to enter a phone number as a string. The input number may contain letters. The program translates a letter (uppercase) or lowercase) to a digit and leaves all other characters intact.

Example execution:

$ python phonePad.py

Enter a string : 1-800-FLOWERS

1-800-3569377

Want to process another phone? y=yes, n=no : y

Enter a string : 1800flowers

18003569377

Want to process another phone? y=yes, n=no : y

Enter a string : 1-800-GOTJUNK

1-800-4685865

Want to process another phone? y=yes, n=no : n

Have a nice day!
