UPC Python SDK allows you to implement accepting payments from Visa/MasterCard on your website
Documentation: Ukrainian, Russian, English

Generate sign for PaymentPage-method:

import upcpayment
from upcpayment.Upc_payment import Upc_payment

#example with additional fields
payment = Upc_payment('1756190', 'E7884956', 100, '980', 'ua', 123, 'description', alt_total_amount=123, alt_currency=978, sd='qwe', delay=1, ref3='something')
payment.generate_signature('path_to_file')
print('1: ', payment.signature)

#example for standard payment
payment = Upc_payment('1756190', 'E7884956', 100, '980', 'ua', 123, 'description')
payment.generate_signature('path_to_file')
print('2: ', payment.signature)

#example of wrong payment
payment = Upc_payment('1756190', 'E7884956', 100, '980', 'ua', 123, 'description', alt_total_amount=123, sd='qwe', delay=1, ref3='something')
payment.generate_signature('path_to_file')
print('3: ', payment.signature)

PurchaseTime generated like this - datetime.datetime.now().strftime("%d%m%Y%H%M%S")
When you make POST-request to gateway - take PurchaseTime from object payment - payment.purchase_time

XML-method

To generate xml with signature use generate_xml_with_signature method to all objects:

xml_with_sign = payment.generate_xml_with_signature('private_key')
