Program execution is faster when manipulating a tuple than it is for the equivalent list. You don’t want data modified. A Python dictionary requires keys that are of an immutable type. Here’s an example: Pytho

a Bar with a str field y and a Tuple[str, str] field hmm a Zap with no fieldsIf type annotations are provided, the constructors will typecheck the arguments (see Typechecking) You can also add your own docstring and methods in the class definition. If you prefer namedtuple-style definit...

#Why Python is Great: Namedtuples#Using namedtuple is way shorter than#defining a class manually:>>>fromcollectionsimportnamedtuple>>> Car = namedtup1e('Car','color mileage')#Our new "Car" class works as expected:>>> my_car = Car('red', 3812.4)>>>my_car.color'red'>>>my_car.mile...

Notes: 1) Base classes can be specified for the new class by passing a tuple of class objects as the first arg to PyClass_New. These can be existing python classes. 2) The second argument passed to PyCFunction_New becomes the "self" arg passed to the C function. This can be any Pyt...
Consider a situation where a function is required to return the sum of two numbers as well as the higher of the two. This means that you need the function to returns two values, both of type Int encapsulated in a tuple. Here’s what it looks like: func sumAndCeiling(a: Int, b: ...
The return value from the processor is a tuple containing two lists. The first list contains any new nodes to be added to the parse tree, and the second list contains error or warning messages to show the user. Processors are defined to return errors instead of raising exceptions because the...
