Reformer
Simple and beautiful library for data formatting/convert/serialize
pip install reformer
Why
There are many great python libraries for validation, serialization and data formatting search as marshmallow, DRF etc. Usually they base on data validation.
Otherwise reformer design only for data formatting, and in a schema you need to define type of transformation and data source.
How to use
To define schema you need to create Reformer base class:
from reformer import Reformer, Field, MapField, MethodField class Schema(Reformer): _fields_ = ('name', 'surname') fullname = Field('name').replace('_', '-') + ' ' + Field('surname') admin = Field('username').at(['admin', 'root']) welcome = MapField('username', { 'admin': 'Hi bro', 'root': 'God?' }) posts_titles = Field('posts').iter(['title']) status = ('http://api.com/get_user_status/' + Field('id', to=str)).handle(requests.get) target = { 'id': 353, 'name': 'John', 'surname': 'Black', 'username': 'admin', 'posts': [ {'title': 'New', 'id': 10}, {'title': 'My first post', 'id': 11}, ] } print(Schema.transform(target)) # OrderedDict([ # ('name', 'John'), # ('surname', 'Black'), # ('fullname', 'John Black'), # ('admin', True), # ('welcome', 'Hi bro'), # ('posts_titles', ['New', 'My first post']), # ('status', 'INIT'), # ])
