Задачи к лекции "Восстановление кривой доходности"

Чтобы определить валюты, для которых Вы будете строить кривые и дату завершения форвардного контракта, запустить функцию ниже с Вашим почтовым ящиком

def getVariant(email):
    ccy = ['NOK', 'SEK', 'DKK', 'EUR']
    h = hash(email)
    ccy1 = ccy[h % 4]
    date = 365 + h%365
    print 'Task 1: 5Y curve for ' + ccy1
    print 'Task 2: FX Forward for USD' + ccy1 + ' with maturity date ' + str(date)
getVariant('[email protected]')

Task 1: 5Y curve for SEK
Task 2: FX Forward for USDSEK with maturity date 524
