The other data types that we have been using (int, float, str, and bool) are all immutable. In an immutable data type, operations that might seem to change a value actually result in the creation of a new object, as illustrated in the simple example at right. First, the statement i ...
The arguments are str and float, respectively, and the return value is a tuple. Yet the interpreter lets it all slide with no complaint at all. Annotations don’t impose any semantic restrictions on the code whatsoever. They’re simply bits of metadata attached to the Python function ...
The field filter defines the permissible field types: Short, Long, Float, Single, Double, Text, Date, OID, Geometry, Blob, Raster, GUID, GlobalID, and XML. More than one value can be supplied to the filter. def getParameterInfo(self): param0 = arcpy.Parameter( displayName="Inpu...
A Value List can be used for Boolean data types. For Boolean data types, the Value List contains two values: true and false. The true value is always the first value in the list. The values specified in the Value List are used inPythonfor specifying the value. See, for example,Add...

A namedtuple-style library for defining immutable sum types in Python. (Get it on PyPI)You may know sum types under a different name – they're also referred to as tagged unions, enums in Rust/Swift, and variants in C++. If you haven't heard about them yet, here's a nice ...
Internally, casting is done using the Python built-in functions for type conversion: bool() complex() float() int() str() bytes() The following example illustrates the difference between coercing traits and casting traits: >>> from traits.api import HasTraits, Float, CFloat >>> class ...
This means, not only can we use objects, but we can define our own classes of objects. A class is just another name for a type in Python. We have been working with types (i.e. classes) since the first chapter of the text. Examples of classes are int , str , bool , float and ...
