Instructions

password_is_valid will check if the password meets a few different conditions. If one of the below conditions is not met then the relevant error/exception should be thrown/raised. Your error/exception message should match one of the following conditions exactly (word-for-word).

• password should exist
• password should be longer than than 8 characters
• password should have at least one lowercase letter
• password should have at least one uppercase letter
• password should at least have one digit
• password should have at least one special character

Next, implement a function called password is ok:

• If the given password meets at least three of the conditions listed above then this function should return true, otherwise it should return false.

• Add a feature: the password is never OK if conditions 1 and 2 are not met.
