代码中出现错误：“TypeError：'list'对象不可调用”

Question

我编写了一段代码，我相信已经完成，但现在当我尝试运行它时，出现以下错误：

Traceback (most recent call last):
  File "D:/python/salaries.py", line 29, in <module>
    pay = totalManagerPay(salary)
TypeError: 'list' object is not callable

我已经做了一些谷歌搜索，但我发现的每个“解决方案”似乎都不适用于我的特定情况，所以我想我自己在这里问。

我的代码在这里：

now = datetime.now()
dt_string = now.strftime("%m/%d/%Y %H:%M:%S")

def totalManagerPay(salary):
    return salary

def totalHourlyPay(hours, rate):
    overtime = max(0, hours - 40)
    return (hoursWorked - overtime) * hourlyPay + overtime * hourlyPay * 1.5

def totalCommissionPay(sales):
    return 350 + 0.057 * sales

def totalPieceWorkerPay(pieces):
    bonus = 500 if pieces > 500 else 0
    return pieces * 4.50 + bonus

totalManagerPay, totalHourlyPay, totalCommissionPay, totalPieceWorkerPay = [], [], [], []

while True:
    payCode = int(input("Enter pay code (0 to quit): "))
    if payCode == 0:
        print("No employees at this time. Thank you.")
        break
    if payCode == 1:
        print("MANAGER SELECTED")
        salary = float(input("Enter gross weekly salary: "))
        pay = totalManagerPay(salary)
        totalManagerPay.append(pay)
    elif payCode == 2:
        print("HOURLY WORKER SELECTED")
        hoursWorked = float(input("Enter number of hours worked: "))
        hourlyPay = float(input("Enter hourly rate: "))
        pay = totalHourlyPay(hoursWorked, hourlyPay)
        totalHourlyPay.append(pay)
        print("Hourly worker's pay is ${pay:.2f}\n")
    elif payCode == 3:
        print("COMMISSION WORKER SELECTED")
        weeklySales = float(input("Enter weekly sales: "))
        pay = totalCommissionPay(weeklySales)
        totalCommissionPay.append(pay)
        print("Commission worker's pay is ${pay:.2f}\n")
    elif payCode == 4:
        print("PIECE BY PIECE WORKER SELECTED")
        piecesProduced = int(input("Enter number of pieces produced: "))
        pay = totalPieceWorkerPay(piecesProduced)
        totalPieceWorkerPay.append(pay)
        print("Piece by Piece worker's pay is ${pay:.2f}\n")
    else:
        print("Error. Please enter a valid code.")
        
if any([totalManagerPay, totalHourlyPay, totalCommissionPay, totalPieceWorkerPay]):

    print("\n******************** ABCD Inc. ************************")
    print("*********** Cumulative Salaries By Pay Code ***********")
    print("Employee Pay Code      Number of Employees     Cumulative Salary")
    print("-----------------------------------------------------------------------------")

    totalSalary, totalEmployees = 0, 0
    
    for payCode, payList in enumerate([totalManagerPay, totalHourlyPay, totalCommissionPay, totalPieceWorkerPay], start=1):
        total = sum(payList)
        totalSalary += total
        totalEmployees += len(payList)
        print(f"        {payCode:<25}{len(payList):<25}{total:.2f}")
        
    print("------------------------------------------------------------------------------")
    print(f"Totals                           {totalEmployees:<34}  {totalSalary:.2f}")
    print("--------------------------------------------------------------------------------")
    print("Date: " + dt_string)
    print("************************************************************************")

我以为错误会出现在调用底部 if 语句中的函数时，但是，当我删除括号时，我仍然收到错误。

您正在定义与您的函数同名的列表。这里：

totalManagerPay, totalHourlyPay, totalCommissionPay, totalPieceWorkerPay = [], [], [], []

与

相同

def totalManagerPay(salary):
    return salary

def totalHourlyPay(hours, rate):
    overtime = max(0, hours - 40)
    return (hoursWorked - overtime) * hourlyPay + overtime * hourlyPay * 1.5

def totalCommissionPay(sales):
    return 350 + 0.057 * sales

def totalPieceWorkerPay(pieces):
    bonus = 500 if pieces > 500 else 0
    return pieces * 4.50 + bonus

将其中任何一个更改为其他名称会有帮助。
