python存款买房1问题解答

假设你每个月都是月初发工资，同时会收到上一个月的存款利息。假设所需的首付款百分比为0.30（30%），
存款年利率interest_rate 为2.25%，每半6 个月加一次薪水，修改你的程序，计算存够首付需要多少个月。
你的程序要给出以下提示并要求用户输入相应的数值：

1. 请输入总房价：total_cost
2. 请输入年薪：annual_salary
3. 请输入月存款比例：portion_saved
4. 每半年加薪比例：semi_annual_raise
5. 请输入存款年利率：
   测试用例：
   请输入总房价：1000000
   请输入年薪：156800
   请输入月存款比例：60
   请输入加薪比例：7

total_cost = float(input()) total_cost为当前房价
annual_salary = float(input()) 年薪
portion_saved = float(input()) / 100 月存款比例，输入30转为30%
semi_annual_raise = float(input()) /100 输入每半年加薪比例，输入7转化为7%

portion_down_payment = 0.3 # 首付比例，浮点数
down_payment = portion_down_payment * total_cost # 首付款
print('首付',down_payment)

current_savings = 0
number_of_months = 0

补充你的代码
month_salary=annual_salary / 12
month_portion=month_salary * portion_saved
计算多少个月才能存够首付款，结果为整数，不足1月按1个月计算，即向上取整
while True:
current_savings=current_savings+month_portion
number_of_months+=1
current_savings=current_savings*(1+0.025/12)
if number_of_months % 6==0:
month_portion=month_portion*(1+semi_annual_raise)
if number_of_months % 12==0:
print(f'第{number_of_months}个月月末有{int(current_savings):,}元存款')
if current_savings>=down_payment:
print(f'需要{number_of_months}个月可以存够首付')
break
请各位学长学姐 为我这个计算有点问题

计算结果应该是这样

total_cost = float(input("请输入总房价: "))  # total_cost为当前房价
annual_salary = float(input("请输入年薪: "))  # 年薪
portion_saved = float(input("请输入月存款比例: ")) / 100  # 月存款比例，输入30转为30%
semi_annual_rise = float(input("请输入加薪比例")) / 100  # 输入每半年加薪比例，输入7转化为7%

portion_down_payment = 0.3  # 首付比例，浮点数
down_payment = portion_down_payment * total_cost  # 首付款
print('首付', down_payment)
month_salary = annual_salary / 12
current_saving = 0  # 存款金额，从0开始
number_of_months = 0

rate = 0.0225 / 12
month = 0
while current_saving < down_payment:
    month += 1
    # current_saving = current_saving * (1 + rate) + month_salary * portion_saved
    if month % 6 == 0:
        month_salary = month_salary * (1 + semi_annual_rise)
    current_saving = current_saving * (1 + rate) + month_salary * portion_saved  # 计算加薪后的工资要放在这里
    if month % 12 == 0:
        print("第{}个月月末有{:,.0f}元存款".format(month, current_saving))
print("需要{}个月可以存够首付".format(month))
