Python 条件if-else语句

我想通过循环，每次价格超过初始价格时，我都会给财富增加1000英镑。每次循环小于初始价格时，我想从财富中减去1000。然后我想在所有迭代之后找到最终值。有人能帮忙吗？

像这样：

prices = [80, 102, 84, 41, 74, 55, 32, 77, 92, 40, 91, 26]
wealth = 5000
init_price = 100
buy = []
sell = []
x = 0

for i, v in enumerate(prices):
    if (v > init_price):
        buy = wealth + 1000
        continue
    else:
        buy_1 = buy.append(buy - 1000)
        continue`

像这样：

prices = [80, 102, 84, 41, 74, 55, 32, 77, 92, 40, 91, 26]
wealth = 5000
init_price = 100
buy = []
sell = []
x = 0

for i, v in enumerate(prices):
    if (v > init_price):
        buy = wealth + 1000
        continue
    else:
        buy_1 = buy.append(buy - 1000)
        continue`

以下是正确的版本：

In [191]: for price in prices: 
     ...:     if price > init_price: 
     ...:         wealth += 1000 
     ...:     else: 
     ...:         wealth -= 1000 
     ...:                                                                                                                                                                                                   

In [192]: wealth                                                                                                                                                                                            
Out[192]: -5000

结果:

prices = [80, 102, 84, 41, 74, 55, 32, 77, 92, 40, 91, 26]
wealth = 5000
init_price = 100
sell = []
x = 0

for v in prices:
    if (v > init_price):
        wealth += 1000
    else:
        wealth -= 1000
print(wealth)
