Use the Variable Annotations to Declare a Variable Without Value in Python For users with Python 3.6+, one may use the Variable Annotations for this situation. Type Annotations were introduced in PEP 484. its main focus was function annotations. However, it also introduced the notion of type co...
Values are somewhere else (e.g. sprinkled all over the heap), and a variable refers (not in the sense of C++ references, more like a pointer minus the pointer arithmetic) to a value. Multiple names can refer to the same value (which is generally a good thing). Python (and other ...
You can use a namedtuple as a workaround to effectively create a constant that works the same way as a static final variable in Java (a Java "constant"). As workarounds go, it's sort of elegant. (A more elegant approach would be to simply improve the Python language --- what sort...
