Program 1 20 pts Using python 2.7.

Step 1 (10 pts) isValidSSN function

PreCondition: one parameter any string Description: returns True if the string is in the form ###-##-#### returns False otherwise.

NOTE: do NOT have ANY print statements in this function!

Step 2 (10 pts) - List of SubLists

Continue asking the user to enter SSNs until they type DONE. Use your function to check to ensure the entry is a valid social security number. If the social security number was valid, ask the user to enter the following information:

Last name

First name

Birth year

Store the information in a list called myEmps that contains sublists with the employee name (last name followed by a comma followed by the first name), age, and social security number. Example of how the myEmployees list will look: [ [ Johnson,Joe, 1970, 501-11-1111 ], [Miller,Mary, 1998, 503-33-3333 ] ] When the user types DONE, print headings followed by the entries in the myEmployees list, one per line.

Use the FORMAT METHOD to ensure that columns are aligned. Do NOT use \t to align! Note: all social security numbers should be printed in the form ###-##-#### Example Output:

Name Birth Year SSN

Joe Johnson 1970 501-11-1111 Mary Miller 1998 503-33-3333
