### Password Test Program Overview

This guide describes how to create a program (`password_test.py`) ensuring that user-entered passwords meet specific security requirements. The program will check if the passwords fulfill the following criteria:

- Minimum of 6 characters
- No spaces or tabs
- At least one uppercase letter
- At least one lowercase letter
- At least one digit
- At least one special character (not a letter, digit, space, or tab)

### Program Components

The program is composed of two functions: `fValidatePwd(pw)` and `main()`.

#### 1. `fValidatePwd(pw)`

- **Purpose**: To validate if a password meets the specified security requirements.
- **Functionality**: 
  - Takes a password as an input parameter.
  - Checks against the stated requirements.
  - Returns `True` if valid, `False` otherwise.
  - Utilizes Python's built-in string functions and methods without printing or asking for user inputs.

#### 2. `main()`

- **Purpose**: To interact with the user, obtain password input, and validate it.
  
- **Functionality**:
  - Displays password requirements to the user.
  - Prompts the user to enter a password.
  - Calls `fValidatePwd()` to validate the entered password.
  - Prints "Password OK." if the password is valid.
  - Prints "Sorry, that is not a valid password." if invalid.
  - Keeps a count of the total and the number of valid passwords attempted.
  - Regardless of validity, asks the user if they want to try another password:
    - If yes (`y`), the loop continues for another attempt.
    - If no (`n`), the program prints "Your score: N valid passwords in M attempts." and exits.

This program ensures that passwords are strong and comply with security standards by systematically checking through a series of criteria and providing user feedback.
