Function Annotations
Function annotations are defined in PEP 3107. They allow attaching data to the arguments and return of a function. The behaviour of annotations is not defined by the language - and left to third party frameworks. For example, a library could be written to handle static typing:

Famous quotes containing the word function:
“Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
—Frank Smith (b. 1928)
