Exercise 3: Validating a Password Function

Create a Python program that asks a user to create a password and then validates that the password meets the following criteria:

• At least one uppercase letter.
• At least one lowercase letter.
• At least one number (0-9).
• At least one special character but only using the following (#$@).

Be sure the validation part of the program is written as a function and called from within the program. Since you have written this is a function, the password validation tool can be placed in many other programs, as needed.
