Demo

Reading data from the Northwind service.

from odata import ODataService
url = 'http://services.odata.org/V4/Northwind/Northwind.svc/'
Service = ODataService(url, reflect_entities=True)
Supplier = Service.entities['Supplier']

query = Service.query(Supplier)
query = query.limit(2)
query = query.order_by(Supplier.CompanyName.asc())

for supplier in query:
    print('Company:', supplier.CompanyName)

    for product in supplier.Products:
        print('- Product:', product.ProductName)

Writing changes. Note that the real Northwind service is read-only and the data modifications do not work against it.

import datetime

Order = Service.entities['Order']
Employee = Service.entities['Employee']

empl = Service.query(Employee).first()

query = Service.query(Order)
query = query.filter(Order.ShipCity == 'Berlin')

for order in query:
    order.ShippedDate = datetime.datetime.utcnow() 
    order.Employee = empl
    Service.save(order)
