A Python typing library for data validation.

Project Description

This library allows type tests and transformation and can be used for data loading, storing and validation.

Usage

Simple type-checking:

import typed

            t1 = typed.int | typed.string

            assert t1.test('abc')
            assert t1.test(u'xyz')
            assert t1.test(30)
            assert not t1.test(1.2)
            assert not t1.test(True)
            assert not t1.test(None)

            t2 = typed.list(typed.int)

            assert t1.test([1, 2, 3])
            assert t1.test([])
            assert not t1.test(['a', 'b', 'c'])

            t3 = typed.list(typed.int | typed.string)

            assert t3.test([1, 'a', 2, 'b'])

            t4 = typed.list(typed.int) | typed.list(typed.string)

            assert t4.test([1, 2, 3])
            assert t4.test(['a', 'b', 'c'])
            assert not t4.test([1, 'a', 2, 'b'])

            t5 = typed.set(1, 2, 3)

            assert t5.test(2)
            assert not t5.test(4)

            t6 = typed.dict({
                            'a': typed.int,
                            'b': typed.bool.optional,
                            'c': (typed.int | typed.none).optional,
                    })
