tuple_schema

Returns a schema that matches a tuple of schemas, with an optional variadic item, e.g.:

from pydantic_core import SchemaValidator, core_schema

schema = core_schema.tuple_schema(
    [core_schema.int_schema(), core_schema.str_schema(), core_schema.float_schema()],
    variadic_item_index=1,
)
v = SchemaValidator(schema)
assert v.validate_python((1, 'hello', 'world', 1.5)) == (1, 'hello', 'world', 1.5)

def tuple_schema(
    items_schema: list[CoreSchema],
    variadic_item_index: int | None = None,
    min_length: int | None = None,
    max_length: int | None = None,
    fail_fast: bool | None = None,
    strict: bool | None = None,
    ref: str | None = None,
    metadata: dict[str, Any] | None = None,
    serialization: IncExSeqOrElseSerSchema | None = None
