Write a Python program that will prompt the user for a valid phone number. The value should only consist of the seven digit phone number (no area code, no spaces, no dashes). You can assume that the user will only enter numeric values. The program should repeatedly ask for a phone number until a value within the valid range has been entered. The first digit of the phone number cannot begin with a zero but may consist of another other number from 1 - 9 e.g., 0123456 IS NOT a valid phone number. The other six digits can consist of values from 0 - 9 e.g. 1, 9999999 IS a valid phone number, e.g.2, 1000000 IS a valid phone number. Once the user does enter a valid phone number then the program should not prompt again but instead should display a brief confirmation message that the value entered was okay e.g., "Thank you valid phone number entered."

Submitting your work:

1. Assignments (source code/'dot-py' file) must be electronically submitted according to [the assignment submission requirements] using [D2L]
2. As a reminder, you are not allowed to work in groups for this class. Copying the work of another student will be regarded as academic misconduct (cheating).  For additional details about what is and is not okay for this class please refer to the following [link].

Aside from input()/print() and functions to convert types: str(), float(), int(), unless you are told otherwise, you will need to write your own code and cannot use other pre-written Python functions/methods.
