Python-I'；我一直在尝试每半年加薪一次（来自麻省理工学院6.0001的PSet_1b），但结果是一样的

PSet_1a-基线

这会提示用户输入他们梦想房屋的成本、他们的工资、他们愿意节省的月薪部分，并返回他们获得首付所需的月数（他们梦想房屋成本的25%）

total_cost=float（输入（'梦想之家是多少？'））
部分首付=0.25
当前储蓄=0
r=0.04
年薪=浮动（输入（“你的工资是多少？”）
部分保存=浮动（输入（'每月保存的金额是多少？'））
月薪=年薪/12.0
预付款金额=总成本*部分预付款
部分金额=月工资*部分保存
月份=0
虽然目前的储蓄答案是通过if报表每6个月更新部分金额，而不是通过年薪的半年度加薪

感谢评论中的Randy。
您正在更新
年薪
，但不是
部分金额
，这是您计算中实际使用的。如果我没有弄错，您在计算中没有使用
半年薪
或
年薪
；因此，这与第一个代码完全相同。@Randy，如果我更新部分金额，那么它将每月添加一次，而不是我计划的每6个月添加一次。您需要在更新年薪的块中更新它，以便它仅在加薪时才更新。
