The meaning of a positional argument is determined by:

The correct answer is A. its position within the argument list. Positional arguments derive their meaning purely from where they appear in the argument list - the first argument maps to the first parameter, the second to the second, and so on, regardless of what value is passed.

Explanation

Positional arguments derive their meaning purely from where they appear in the argument list - the first argument maps to the first parameter, the second to the second, and so on, regardless of what value is passed.

Why the distractors are wrong:

  • B (its value): The value a positional argument holds doesn't tell the function what role it plays - 42 could be a width, an age, or an index depending on position.
  • C (its connection with existing variables): Positional arguments have no inherent link to external variables; their parameter binding comes from order alone.
  • D (the argument's name specified along with its value): That describes a keyword (named) argument, e.g., func(width=42) - the opposite of positional.

Memory tip: Think of seats on a bus - seat 1 is always the driver's seat no matter who sits there. Position defines the role, not the person (value) in the seat.
