An exploration into how we could support int64 as well as float64 as a first class type in Pulumi. There's some inherit trickiness with this because we use JSON in a few places, state files most obviously but `PropertyValue` on the wire is using the protobuf `Struct` and `Value` types which are just mappings to JSON as well. JSON doesn't have an int64 type, and while the Go JSON marshaller can read/write int64s it's not a great behaviour to rely on given mixed support for that across languages. Further the protobuf `Value` type only supports float64s. So we support integers similar to our other special types (like assets) and wrap them in an object with a special signature field. The value itself is either a number (if it can safely roundtrip to float64 and back again) or a string. Providers, SDKs and the engine communicate support for integers via `AcceptsIntegers` fields in their interfaces (or similar). When transmitting to a peer that doesn't support integers (e.g. an old SDK, or old provider) all integer values are mapped back to standard number values. As this changes the serialisation of property values in the state file it will trigger errors if old engines try to load a state file containing integers. |

Pulumi Python SDK
The Pulumi Python SDK (pulumi) is the core package used when writing Pulumi programs in Python. It contains everything that you’ll need in order to interact with Pulumi resource providers and express infrastructure using Python code. Pulumi resource providers all depend on this library and express their resources in terms of the types defined in this module.
The Pulumi Python SDK requires a supported version of Python.
note: pip is required to install dependencies. If you installed Python from source, with an installer from python.org, or via Homebrew you should already have pip. If Python is installed using your OS package manager, you may have to install pip separately, see Installing pip/setuptools/wheel with Linux Package Managers. For example, on Debian/Ubuntu you must run sudo apt install python3-venv python3-pip.

Pulumi Programming Model
The Pulumi programming model defines the core concepts you will use when creating infrastructure as code programs using Pulumi. Architecture & Concepts describes these concepts with examples available in Python. These concepts are made available to you in the Pulumi SDK.
The Pulumi SDK is available to Python developers as a Pip package distributed on PyPI . To learn more, refer to the Pulumi SDK Reference Guide.
The Pulumi programming model includes a core concept of Input and Output values, which are used to track how outputs of one resource flow in as inputs to another resource. This concept is important to understand when getting started with Python and Pulumi, and the [Inputs and Outputs] (https://www.pulumi.com/docs/intro/concepts/inputs-outputs/)documentation is recommended to get a feel for how to work with this core part of Pulumi in common cases.
The Pulumi Python Resource Model
Like most languages usable with Pulumi, Pulumi represents cloud resources as classes and Python programs can instantiate those classes. All classes that can be instantiated to produce actual resources derive from the pulumi.Resource class.
