修复“Python Payroll Program”中的错误

1.用户在使用Python编写的工资计算程序时遇到了问题，该程序旨在计算一组员工的工资。用户报告了关于while语句的问题。在代码中，用户使用了while (True)语句来无限循环，并使用if status != 1 or 2:条件来检查婚姻状况。然而，这样的写法会导致循环永远无法退出，因为条件总是成立。

2、解决方案 为了修复这个问题，需要将if status != 1 or 2:条件替换为if status not in (1, 2):。

while True:
    status = eval(input("Are they single(1) or married(2)? \n"))
    if status not in (1, 2):
        break

现在，条件将检查状态是否不是1或2，这样循环将能够退出。

以下是修复后的代码：

def computeGrossPay(hours, rate):
    if hours > 40:
        grossPay = (40 * rate) + ((hours - 40) * 1.5 * hours)
    else:
        grossPay =  hours * rate
    return grossPay

def computeTaxAmount(status, grossPay):
    if status == 1:
            if grossPay <= 42:
                taxAmount = 0
            elif grossPay > 42 and grossPay <= 214:
                taxAmount = (grossPay - 15) * .1
            elif grossPay > 214 and grossPay <= 739:
                taxAmount = 17.2 + ((grossPay - 214) * .15)
            elif grossPay > 739 and grossPay <= 1732:
                taxAmount = 95.95 + ((grossPay - 739) * .28)
            elif grossPay > 1732 and grossPay <= 2566:
                taxAmount = 344.2 + ((grossPay - 1732) * .28)
            elif grossPay > 3566 and grossPay <= 7703:
                taxAmount = 857.72 + ((grossPay - 3566) * .33)
            elif grossPay > 7703 and grossPay <= 7735:
                taxAmount = 2222.93 + ((grossPay -7703) * .35)
            elif grossPay > 7735:
                taxAmount = 2234.13 + ((grossPay - 7735) * .396)
    elif status == 2:
            if grossPay <= 160:
                taxAmount = 0
            elif grossPay > 160 and grossPay <= 503:
                taxAmount = (grossPay - 160) * .1
            elif grossPay > 503 and grossPay <= 1554:
                taxAmount = 34.3 + ((grossPay - 503) * .15)
            elif grossPay > 1554 and grossPay <= 2975:
                taxAmount = 191.95 + ((grossPay - 1554) * .28)
            elif grossPay > 2975 and grossPay <= 4449:
                taxAmount = 547.2 + ((grossPay - 2975) * .28)
            elif grossPay > 4449 and grossPay <= 7820:
                taxAmount = 959.92 + ((grossPay - 4449) * .33)
            elif grossPay > 7820 and grossPay <= 8813:
                taxAmount = 2072.35 + ((grossPay -7820) * .35)
            elif grossPay > 8813:
                taxAmount = 2419.9 + ((grossPay - 8813) * .396)
    return taxAmount

def computeNetPay(grossPay, taxAmount):
    netPay = grossPay - taxAmount
    return netPay

def main():
    totalGrossPay = 0
    print("Welcome to the Payroll Program")
    counter = eval(input("How many employees will be entered? \n"))
    for i in range(counter):
        name = input("What are the first and last names of the employee? \n")
        id = input("What are the last four numbers of his/her Social Security Number? \n")
        hours = eval(input("How many hours did they work? \n"))
        rate = eval(input("What was the rate? \n"))
        while True:
            status = eval(input("Are they single(1) or married(2)? \n"))
            if status not in (1, 2):
                break
        grossPay = computeGrossPay(hours, rate)
        taxAmount = computeTaxAmount(status, grossPay)
        netPay = computeNetPay(grossPay, taxAmount)
        totalGrossPay = totalGrossPay + grossPay
        averageGrossPay = totalGrossPay / counter

        print("The ID is ", id)
        print("The name is ", name, ".")
        print("This employee worked ", hours, " hours.")
        print("The hourly rate was ", rate)
        print("The gross pay was $", grossPay)
        print("The tax amount withheld for the week is $", taxAmount)
        print("The net pay is $", netPay)
    print("The total gross pay was $", totalGrossPay)
    print("The average gross pay was $", averageGrossPay)

main()

这样，代码可以正确计算员工的工资。
