从python中的另一个函数调用变量

Question

我已经定义了这两个函数，我需要从第一个函数中调用函数2中的收入和津贴，基本上我想计算函数2中的finalIncome（注释该行代码）。 这是代码：

def personalAllowance():
    income = int(input("Enter your annual salary: £"))
    allowance = 10600
    if(income>100000):
        for i in range (100000, income):
            if(income%2==0):
                allowence = allowence - 0.5
                if(allowence<0):
                    allowence = 0
        print("Personal Allowance = " + str(allowence))
    else:
        print("Personal Allowance = " + str(allowence))
    return (income , allowance)


def incomeTax():
    print("\n")
    #finalIncome = income - allowence
    print(finalIncome)
    taxBill = 0
    if(finalIncome <= 31785):
        taxBill = finalIncome * (20/100)
    elif(finalIncome > 31785 and finalIncome < 150000):
        taxBill = finalIncome * (40/100)
    elif(finalIncome >= 150000):
        taxBill = finalIncome * (45/100)
    print (taxBill)


incomeTax()

Answer 1

您只需要调用personalAllowance并将返回值分配给某些对象即可。

例如：

income, allowance = personalAllowance()

Answer 2

保存对这些值的引用，然后减去它们：

income, allowance = personalAllowance()
finalIncome = income - allowance

Answer 3

由于您实际上并不需要“收入”或“津贴”，因此无需返回元组，只需返回与我相比较的地方所示的差额即可

def personalAllowance():
        income = int(input("Enter your annual salary: £"))
        allowance = 10600
        if(income>100000):
            for i in range (100000, income):
                if(income%2==0):
                    allowence = allowence - 0.5
                    if(allowence<0):
                        allowence = 0
            print("Personal Allowance = " + str(allowence))
        else:
            print("Personal Allowance = " + str(allowence))
        return income - allowance ## Just return the difference



def incomeTax():
    print("\n")
    finalIncome = personalAllowance()  ## This will return difference
    print(finalIncome)
    taxBill = 0
    if(finalIncome <= 31785):
        taxBill = finalIncome * (20/100)
    elif(finalIncome > 31785 and finalIncome < 150000):
        taxBill = finalIncome * (40/100)
    elif(finalIncome >= 150000):
        taxBill = finalIncome * (45/100)
    print (taxBill)


incomeTax()
