Problem statement
Write a function multiply(a, b) that returns the product of a and b. Add a simple docstring to the function exactly: "Multiply two numbers and return the product." Ensure the function behavior matches the docstring and that multiply.__doc__ returns that exact string.
Task
Define a function with an exact docstring and correct behavior so learners practice writing documentation strings.
Examples
Input format
Two numeric values (integers or floats).
Output format
Return the numeric product of the two inputs.
Constraints
Include the exact docstring: "Multiply two numbers and return the product." The function must return a*b.
