我希望它打印一个表格，在将每行中的每个结果相加之前显示它们。 像这样：
ID,Table Sales,Desk Sales,Chair Sales
413 23.0 52.0 532.0
5 32523.0 5323.0 5.0
325 25.0 3253.0 23.0
Total,32571.00,8628.00,560.00
Commission Table:
ID,Table Commission,Desk Commission,Chair Commission
413 2.30 7.80 26.60
5 3252.30 798.45 0.25
325 2.50 487.95 1.15
Total,3257.10,1294.20,28.00
但我不断收到这个：

我一直只得到我的销售、佣金和销售人员 ID 的最后输入结果。

这是一个很大的问题，我将把它分解成更小的部分来展示解决方案。
下面的代码基本上就是你的代码想要做的事情（我描述了此后的所有功能）
def main():
salepersons, sales, commissions = [], [], []
saleperson = int(input("Please input salesperson ID or -1 to end: "))
while saleperson > -1:
table_sales, desk_sales, chair_sales = get_sales()
table_commission, desk_commission, chair_commission = get_commissions(table_sales, desk_sales, chair_sales)
salepersons.append(saleperson)
sales.append((table_sales, desk_sales, chair_sales))
commissions.append((table_commission, desk_commission, chair_commission))
saleperson = int(input("Please input another salesperson ID or -1 to end: "))
print_data(salepersons, sales, commissions)
if __name__ == "__main__":
main()
但是，当您向用户询问数据时，您从未将数据附加到列表中，因此每当您输入任何内容时，您只需删除之前的输入即可
while sale_person != -1: ... # some code inside the loop ... # some code outside the loop sale_list.append(sale_info) # appending after the loop commission_list.append(commission_info) # appending after the loop
这会导致仅保留最后的输入。解决这个问题应该足以解决您的问题。
我将尝试改进您的其余代码，同时给出更改的理由。我希望这有帮助。
def get_sales():
table_sales = get_sales_for_item("table")
desk_sales = get_sales_for_item("desk")
chair_sales = get_sales_for_item("chair")
return table_sales, desk_sales, chair_sales
询问销售数量的代码对于任何商品都是相同的，因此为了避免重复，我将此代码放在一个名为
get_sales_for_itemdef get_sales_for_item(item):
sales = int(input(f"Enter {item} sales: "))
while sales < 0:
print(f"Enter valid {item} sales")
sales = int(input(f"Enter {item} sales: "))
return sales
这只是询问销售额，直到获得有效数字并将该数字返回给调用函数
def get_commissions(table_sales, desk_sales, chair_sales):
table_commission = get_commissions_for_item("table", table_sales)
desk_commission = get_commissions_for_item("desk", desk_sales)
chairs_commission = get_commissions_for_item("chair", chair_sales)
return table_commission, desk_commission, chairs_commission
同样，我已将向用户询问佣金的代码放在通用函数中
get_commissions_for_itemdef get_commissions_for_item(item, sales):
if item == "table":
commission = 10 if sales <= 500 else 20 if sales < 1000 else 30 if sales < 1500 else 40
elif item == "desk":
commission = 20 if sales <= 500 else 30 if sales < 1000 else 40 if sales < 1500 else 50
elif item == "chair":
commission = 30 if sales <= 500 else 40 if sales < 1000 else 50 if sales < 1500 else 60
return commission
这里我使用三元运算符而不是链接 ifs，但它执行与代码中相同的检查。
def print_data(salepersons, sales, commissions):
print("\nSales Table")
print("\t".join(["ID", "Tables", "Desks", "Chairs"]))
print("-" * 40)
for sp, (tb_rev, dk_rev, ch_rev) in zip(salepersons, sales):
print("\t".join(str(x) for x in [sp, tb_rev, dk_rev, ch_rev]))
tables_total = sum([sale[0] for sale in sales])
desks_total = sum([sale[1] for sale in sales])
chairs_total = sum([sale[2] for sale in sales])
print("\t".join(str(x) for x in ["TOTAL", tables_total, desks_total, chairs_total]))
print("\nCommission Table")
print("\t".join(["ID", "Tables", "Desks", "Chairs"]))
print("-" * 40)
for sp, (tb_com, dk_com, ch_com) in zip(salepersons, commissions):
print("\t".join(str(x) for x in [sp, tb_com, dk_com, ch_com]))
tables_total = sum([commi[0] for commi in commissions])
desks_total = sum([commi[1] for commi in commissions])
chairs_total = sum([commi[2] for commi in commissions])
print("\t".join(str(x) for x in ["TOTAL", tables_total, desks_total, chairs_total]))
这里我接收
