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:
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
