Password Validator

You are tasked to create a password validation system. If the password does not meet the following criteria, a ValueError should be raised with an appropriate error message of what went wrong (see the examples):

  1. The password must have at least 8 characters.

  2. The password must contain at least 1 number.

  3. The password must include at least 1 uppercase letter.

  4. The password must have at least one special character (.,:;!?()[]{}<>+=-*%/$^|@#&_~`).

If the password passes all checks, the program should print: Your password is valid!
