One thing I need to learn before I go further with Python is to thoroughly learn the logic rules. Sure, you can just learn the concepts but being able to write actual code will mean memorising these rules.

  • not False = True

  • not True = False

  • True or False = True

  • True or True = True
  • False or True = True

  • False or False = False

  • True and False = False

  • True and True = True
  • False and True = False

  • False and False = False

  • not (True or False) = False

  • not (True or True) = False
  • not (False or True) = False

  • not (False or False) = True

  • not (True and False) = True

  • not (True and True) = False
  • not (False and True) = True

  • not (False and False) = True

  • 1 != 0 True

  • 1 != 1 False
  • 0 != 1 True

  • 0 != 0 False

  • 1 == 0 False

  • 1 == 1 True
  • 0 == 1 False
  • 0 == 0 True
