Question

此处的目标是计算销售人员出售两辆汽车（每种类型的任何一辆汽车）的总薪资。当他们出售新车时，他们赚了1,500美元。当他们出售二手车时，他们收取车辆价格的5％的佣金。我必须提示销售人员输入每辆车的类型和售价。然后，应显示销售员的总销售额和总工资。我不了解first_pay

有什么问题

firstType = input('What is the first type of vehicle you are selling? ')
firstPrice = int(input('What is the price of the first vehicle? '))
secondType = input('What is second type of vehicle you are selling? ')
secondPrice = int(input('What is the price of the second vehicle? '))

if firstType == 'new':
    first_pay = 1500
elif firstType == 'used':
    first_pay = firstPrice * .05

if secondType == 'new':
    second_pay = 1500
elif secondType == 'used':
    second_pay = secondPrice * .05

    totalPay = first_pay + second_pay
    totalSales = firstPrice + secondPrice
    print('Total sales: $', format(totalSales, ',.2f'), sep='')
    print('Total pay: $', format(totalPay, ',.2f'), sep='')

Answer 1

程序假定print语句是else if语句的一部分。可行

firstType = input('What is second type of vehicle you are selling? ')
firstPrice = int(input('What is the price of the first vehicle? '))
secondType = input('What is second type of vehicle you are selling? ')
secondPrice = int(input('What is the price of the second vehicle? '))

if firstType == 'new':
    first_pay = 1500
elif firstType == 'used':
    first_pay = firstPrice * .05

if secondType == 'new':
    second_pay = 1500
elif secondType == 'used':
    second_pay = secondPrice * .05

totalPay = first_pay + second_pay
totalSales = firstPrice + secondPrice
print('Total sales: $', format(totalSales, ',.2f'), sep='')
print('Total pay: $', format(totalPay, ',.2f'), sep='')

Answer 2

看起来firstType从未定义，因此if else块的两个路径都评估为false，导致未设置first_pay。

为什么不能定义我的first_pay？我的second_pay工作正常
