The ID scalar type represents a unique identifier, often used to refetch an object or as key for a cache. The ID type appears in a JSON response as a String; however, it is not intended to be human-readable. When expected as an input type, any string (such as "4") or integer (such as 4) input value will be accepted as an ID.


The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^31 - 1) and 2^31 - 1 since represented in JSON as double-precision floating point numbers specifiedby IEEE 754.


The Float scalar type represents signed double‐precision fractional values as specified by IEEE 754.

Use of this type is not recommended as you lose the benefits of having a defined, static
schema (one of the key benefits of GraphQL).

Leverages the internal Python implementation of UUID (uuid.UUID) to provide native UUID objects
