# Path Parameters and Numeric Validations

In the same way that you can declare more validations and metadata for query parameters with `Query`, you can declare the same type of validations and metadata for path parameters with `Path`.

## Import Path

First, import `Path` from `fastapi`, and import `Annotated`:

//// tab | Python 3.10+

```Python hl_lines="1  3"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
```

	lval, lerr := e.Left.evalNode(r, tableAlias)
	if lerr != nil || len(e.Right) == 0 {
		return lval, lerr
	}

	// Process remaining child nodes - result must be
	// numeric. This AST node is for terms separated by + or -
	// symbols.
	for _, rightTerm := range e.Right {
		op := rightTerm.Op
		rval, rerr := rightTerm.Right.evalNode(r, tableAlias)
		if rerr != nil {
			return nil, rerr
