有没有一种方法可以根据文本文件中特定位置上的内容累加金额？

Question

我已经尝试

totalValue = 0 bagsChecked = 0

for x in range(len(volunteerList)):
    record = volunteerList[x]

    if record[1] == "1 pence":
        amount = 1.00
    elif record[1] == "2 pence":
        amount = 1.00
    elif record[1] == "5 pence":
        amount = 5.00
    elif record[1] == "10 pence":
        amount = 5.00
    elif record[1] == "20 pence":
        amount = 10.00
    elif record[1] == "50 pence":

        amount = 10.00
    elif record[1] == "1 pound":
        amount = 20.00
    else:
        amount = 20.00

    totalValue = totalValue + amount
    bagsChecked = bagsChecked + 1

    print("Bags checked: ",bagsChecked)
    print("Total Value: ",totalValue)'''

有没有一种方法可以解决此问题，以便显示准确的托运行李数量和总价值。

我不确定这将运行，因为我不知道您的数据是什么样子，但是您可以尝试执行以下操作：

total_value = 0
total_bags = 0

for rec in volunteerList:

    if "pence" in rec[1]:
        total_value += float(rec[1].split[' '][0])
    if "pound" in rec[1]:
        total_value += 20 * float(rec[1].split[' '][0])

    total_bags += 1

    print("Bags checked: {}".format(total_bags))
    print("Total Value: {}".format(total_value))

这假设volunteerList中的每个条目都是一个包含“便士”或“英镑”的字符串。然后，我们将字符串拆分并保留计数的数字部分。
