    True == 1
    False == 0
    every object that doesnt overrides the __bool__ or the __eq__ method is usually True.

    Type coercion is debatable but most of the time pretty cool. isinstance(True, int) == True is just plain stupid

    And this is why i always say that learning c as a first language will help a lot in the future

    Yeah, but not languages follow 1 == True, for a good reason

    It's quite reasonable I think. Allows for some Boolean sorcery like additions and multiplications

    Edit: don't do that tho. Your senior dev will murder you

    @Excessive Keep in mind that most of the time that's highly implementation dependent

    yup

    several langs use 0 and 1 internally as False and True, respective, so this isn't surprising.
