statjc typing == fast & cumbersome ↕ gradual typing ↕ dynamic typing == easy & slowish
– Blog post by Jeremy Siek (Univ. of Indiana/USA): htups:/ /wphomes.soic.indiana.edu/jsiek/what-is-gradual-typing/ – Basis for Python’s PEP-484 type annotatjons
– dynamic typing for ease of development – optjonal statjc typing for safety, speed, documentatjon
– don’t require them where they get in the way

int
– “Gradual Typing for Python”
– Productjon proven – Widely used
– Keeps focus on functjonality, not boilerplate – Allows moving freely between Python and C/C++ – As pythonic as you want, as low-level as you need
