Description

The existing partial examples in the Canvas guide use add(x, y), which is commutative (add(4, 2) == add(2, 4)). This makes it unclear whether delay() prepends or appends its arguments to the partial signature.

This adds a .. note:: with a subtract example that makes the prepend behavior obvious:

>>> partial = subtract.s(10)    # incomplete: second arg only
>>> partial.delay(30)           # -> subtract(30, 10) = 20

Since subtraction is not commutative, the reader can immediately see that delay(30) prepends 30 as the first argument.

Fixes #6484

Pull request overview

This PR addresses Issue #6484 by adding a .. note:: block in the Canvas guide's "Partials" section. It introduces a subtract example to make the argument-prepend semantics of delay()/apply_async() unambiguous, since the existing add example is commutative and doesn't reveal the argument ordering.

Changes:

  • Adds a .. note:: block explaining that extra args passed to delay/apply_async are prepended to signature args.
  • Illustrates the concept with a non-commutative subtract(x, y) -> x - y task example.
  • Provides explanatory prose noting that partial.delay(30) results in subtract(30, 10), not subtract(10, 30).

Add an explicit @app.task definition for subtract(x, y) so the example
is self-contained and readers don't wonder where the task comes from.
Remove the separate task definition code block and instead describe
subtract inline as 'subtract(x, y) -> x - y', making it clear this
is a hypothetical example without needing a full definition.

Good point! I've removed the separate task definition block and instead described it inline as subtract(x, y) -> x - y in the prose, making it explicitly hypothetical without needing a full definition. This keeps the example self-contained while avoiding an undefined symbol.
