從另一個函數調用變量在python

Question

我已經定義這兩個功能，我需要從所述第一函數調用函數2收入和津貼，基本上我要計算的finalIncome在功能2（該行代碼被註釋） 。繼承人代碼：

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

保存這些值的引用，然後減去他們：

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

Answer 2

您只需撥打personalAllowance並將返回值分配給某物。

例如：

income, allowance = personalAllowance() 

Answer 3

既然你實際上並不需要的「收入」或「補貼」，而不是返回一個元組，只是返回差異顯示在我已經commetned

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()
