substitution format expressions permalink

Substitutions, or interpolation, allow you to use formatting expressions to manipulate values dynamically at run-time. Use this for type-safe assignment, string concatenation, simple string formatting replacement & python expressions for more complex logic like min, max, abs or constructing more complex conditional boolean evaluation expressions.

You can use any of the following anywhere that supports substitutions.
