PythonJJ點睇3.6既Variable Annotations update
https://www.python.org/dev/peps/pep-0526/
Type annotation can be added to an assignment statement or to a single expression indicating the desired type of the annotation target to a third party type checker:
my_var: int
my_var = 5 # Passes type check.
other_var: int = 'a' # Flagged as error by type checker,
# but OK at runtime.
本來3.4，呢個update搞到我想轉3.6
