Annotype: Python 3 annotations and marshmallow
Annotype combines Python 3 annotations and Marshmallow for powerful validation of function arguments.
from annotype import annotyped
from marshmallow import (
Schema,
fields
)
class PersonSchema(Schema):
firstname = fields.Str(required=True)
lastname = fields.Str(required=True)
@annotyped()
def salute(person: SampleSchema):
print 'Hello {} {}'.format(person['firstname'], person['lastnamename'])
person = dict(firstname='John')
# This will raise a ValidationError because lastname is not defined
salute(person)
@annotyped()
def welcome(firstname: fields.Str(), lastname: fields.Str()):
print 'Welcome {} {}'.format(firstname, lastname)
# This will also raise a ValidationError because lastname is not a string
welcome('Jane', 1)In short, annotype allows you to validate data using the powerful marshmallow library and the Python 3 annotations.
