PyYep is a python schema builder for value parsing and validation. Define a schema, transform a value to match and validate the inputs with existing validator or custom functions.

PyYep is heavily inspired by Yup

Install

pip install PyYep

Usage

You define and create schema objects with its inputs and validation methods. Then use the verify method to check the schema. A ValidationError will be raised if some input value does not match the validation.

from PyYep import Schema, InputItem, ValidationError

schema = Schema([
    InputItem('name', input_object, 'path-to-input_object-value-property-or-method').string().email(),
    InputItem('name', input_object, 'path-to-input_object-value-property-or-method').number().min(10).max(100),
], abort_early=False) 

// check validity

try:
    result = schema.validate()
    # handle result
except ValidationError:
    # handle fail
