根据for循环产生的数字计算总数（运行总数）

Question

我的任务是计算如果一个人的工资从每天1美分开始，每天翻番，他会得到多少钱。在

days = int(input("How many days will you work for pennies a day?"))
total_amount = ((2 ** (days - 1)) / 100)
print("Days Worked | Amount Earned That Day")
for num in range(days):
    total_amount = format((2 ** (num) / 100), ',.2f')
    print(num + 1, "|", "$", total_amount)

如果我输入15天，我可以看到每天的工资，但我需要15天的总收入。在

Answer 1

记录今天的工资和前一天的工资。以前计算今天工资和今天工资合计

init_sal = .01
total = 0
today_sal = 0
days = int(input("How many days will you work for pennies a day?"))

for x in range(1, days+1):
    if x == 1:
        today_sal = init_sal
        prev_sal = today_sal
    else:
        today_sal = prev_sal * 2
        prev_sal = today_sal
     total += today_sal
     print ('$', today_sal)

print (total)

Answer 2

I need the total amount earned over the 15 days

作为一个标准的for循环示例，您需要在每次迭代中求和。要实现这一点，您可以用0初始化变量（total_accumulated），然后将每次迭代的每个中间结果添加到此变量中，循环完成后，您将打印出最终的累加结果，如下所示（对原始代码的最小编辑）：

days = int(input("How many days will you work for pennies a day?"))
total_amount = ((2 ** (days - 1)) / 100)
total_accumulated = 0
print("Days Worked | Amount Earned That Day")
for num in range(days):
    current_pay = (2 ** (num) / 100)
    total_accumulated += current_pay
    total_amount = format(current_pay, ',.2f')
    print(num + 1, "|", "$", total_amount)
print("Total accumulated:", str(total_accumulated))

正如@NiVeR在对您的问题的评论中所指出的，这可以直接计算出来，这个答案只针对带有循环的示例，因为这看起来像是典型的练习案例。在
