from __future__ import print_function
from numpy import *
from datetime import date
from pyimsl.math.nextCouponDate import nextCouponDate, DAY_CNT_BASIS_ACTUAL365, SEMIANNUAL

frequency = SEMIANNUAL
basis = DAY_CNT_BASIS_ACTUAL365

settlement = date(1996, 11, 11)
maturity = date(2009, 3, 1)

ncdate = nextCouponDate(settlement, maturity,
                        frequency, basis)
print("The next coupon date after the settlement date is ", ncdate)
