输入贷款总量和贷款年数,显示每个月的还款数额和总还款数额
不是很理解"for each monthly interst rate starting from 4 to 8 in increments of 1",请解释
先粘出来写了开头的代码：
import os
class LOAN_ERROR(Exception):
def __init__(self, message):
self._message = message
def __str__(self):
return self._message
if __name__ == "__main__":
try:
total_loan_money = raw_input("loan amount: ")
loan_period = raw_input("loan period (year): ")
if not isinstance(loan_period, int) or loan_period < 0:
raise LOAN_ERROR("Please provide a positive number.")
