问题描述
部分 答: 众议院 狩猎 您已经从麻省理工学院毕业了 现在有一个很棒的工作!  您 移动 到 的 圣 旧金山 湾 区域和 确定 也就是说 你 想 到 启动 保存 到 购买  A 房子。 作为住房 价格 非常高
湾 区, 你 实现 你 是 去 到 具有 到 保存 为 数 年 之前 你
可&NBSP ;负担 到 使  A 。房子 
以 部分  A, 我们 是 去 到 确定 如何 长&NBSP的 下 支付 在&NBSP ;它 将 取 你 到 保存 足够 钱 到 使 的 下 支付 给予 的 下面的 假设:
1__。致电 your dream home total_cost。
2__。调用 的 所述 部分&NBSP的 成本 所需 对于  A 向下 支付  portion_down_payment 对于 简单起见, 假定 即  portion_down_payment  =  0.25 (25%) 。
3__。呼叫 的 量 也就是说 你 具有 保存 因此 远  current_savings 你 启动 与  A 电流 储蓄 的  $ 0 
4__ 。假定 也就是说 你 投资 您的 电流 储蓄 在刀刃上, 与 的 年 返回 的  R (以 其他 也就是说,  AT 的 末 的 每个 本月, 你 接收 的 另外  current_savings * R / 12 基金 到 把 到 您的 储蓄  -  的  12 是 因为  R 是 的 年 费率)。 假设您的投资获得 = 0.04 (4%)。
5__。假设您的年薪 是 annual_salary。
6__。假定 你 是 去 到 奉献  A 某些 量 的 您的 工资 每个 当月 到 保存 为 的 下 支付 呼叫 也就是说  portion_saved 这个 变量 应该是 十进制 形式 (即 0.1 对于10%)。
7__。 AT 的 末 的 每个 当月, 您的 储蓄 将 是 增加 由 的 回归 在 您的 投资, 加  A 百分比 您的 的&NBSP ;月薪 (年薪 / 12)。
 撰写  A 程序 到 计算 如何 许多 几个月 它 将 取 你 到 保存 最多 足够 钱 为  A 下&NBSP ;支付 你 将 想 您的 主 变量 到 是 花车, 所以 你 应该 投 用户NBSP;输入 到 浮动  1
我的尝试:
Part A: House Hunting You have graduated from MIT and now have a great job! You move to the San Francisco Bay Area and decide that you want to start saving to buy a house. As housing prices are very high in the
Bay Area, you realize you are going to have to save for several years before you
can afford to make the down payment on a house.
In Part A, we are going to determine how long it will take you to save enough money to make the down payment given the following assumptions:
1__. Call the cost of your dream home total_cost.
2__. Call the portion of the cost needed for a down payment portion_down_payment. For simplicity, assume that portion_down_payment = 0.25 (25%).
3__. Call the amount that you have saved thus far current_savings. You start with a current savings of $0.
4__. Assume that you invest your current savings wisely, with an annual return of r (in other words, at the end of each month, you receive an additional current_savings*r/12 funds to put into your savings – the 12 is because r is an annual rate). Assume that your investments earn a return of r = 0.04 (4%).
5__. Assume your annual salary is annual_salary.
6__. Assume you are going to dedicate a certain amount of your salary each month to saving for the down payment. Call that portion_saved. This variable should be in decimal form (i.e. 0.1 for 10%).
7__. At the end of each month, your savings will be increased by the return on your investment, plus a percentage of your monthly salary (annual salary /12).
Write a program to calculate how many months it will take you to save up enough money for a down payment. You will want your main variables to be floats, so you should cast user inputs to floats. 1
What I have tried:
total_cost=int(input('enter a value to buy a house:'))
down_payment=total_cost*25/100
total_cost=total_cost-down_payment
annual_sallery=int(input('enter your annual sallery:'))
y=int(input('enter how much % of your sallry you invested per mounth in this program:'))
mounth_proper_saving=annual_sallery*y/1200
x=mounth_proper_saving
mounth_sallery=annual_sallery/12
saving=mounth_sallery
mounth=1 #because of at the end of 1st month you have only mounth_proper_saving
while(mounth_proper_saving<down_payment):
mounth_proper_saving+=x
mounth_proper_saving+=saving
mounth+=1
current_saving=0
while(total_cost>current_saving):
mounth+=1
current_saving+=current_saving*0.04+saving
print(mounth)
推荐答案
0.
4__。假定&NBSP;也就是说&NBSP;你&NBSP;投资&NBSP;您的&NBSP;电流&NBSP;储蓄&NBSP;在刀刃上,&NBSP;与&NBSP;的&NBSP;年&NBSP;返回&NBSP;的&NBSP; R&NBSP;(以 其他&NBSP;也就是说,&NBSP; AT&NBSP;的&NBSP;末&NBSP;的&NBSP;每个&NBSP;本月,&NBSP;你&NBSP;接收&NBSP;的&NBSP;另外&NBSP; current_savings * R / 12&NBSP;基金&NBSP;到&NBSP;把&NBSP;到&NBSP;您的&NBSP;储蓄&NBSP; - &NBSP;的&NBSP; 12&NBSP;是&NBSP;因为&NBSP; R&NBSP;是&NBSP;的&NBSP;年&NBSP;费率)。 假设您的投资获得 = 0.04 (4%)。
5__。假设您的年薪 是 annual_salary。
6__。假定&NBSP;你&NBSP;是&NBSP;去&NBSP;到&NBSP;奉献&NBSP; A&NBSP;某些&NBSP;量&NBSP;的&NBSP;您的&NBSP;工资&NBSP;每个&NBSP;当月&NBSP;到&NBSP;保存&NBSP;为&NBSP;的&NBSP;下&NBSP;支付&NBSP;呼叫&NBSP;也就是说&NBSP; portion_saved&NBSP;这个&NBSP;变量&NBSP;应该是 十进制 形式 (即 0.1 对于10%)。
7__。 AT&NBSP;的&NBSP;末&NBSP;的&NBSP;每个&NBSP;当月,&NBSP;您的&NBSP;储蓄&NBSP;将&NBSP;是&NBSP;增加&NBSP;由&NBSP;的&NBSP;回归&NBSP;在&NBSP;您的&NBSP;投资,&NBSP;加&NBSP; A&NBSP;百分比&NBSP;您的&NBSP;的&NBSP ;月薪 (年薪 / 12)。
