Calling variable from another function in python

Question

I have defined these two functions and I need to call income and allowance in function 2 from the first function, basically I want to calculate the finalIncome in function 2 (that line of code is commented). Heres the code:

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

Save references to those values and then subtract them:

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

Answer 2

You just have to call personalAllowance and assign the return value to something.

For example:

income, allowance = personalAllowance()

Answer 3

Since you don't actually need the "income" or "allowance", instead of returning a tuple, just return the difference as shown where I have 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()

• Salman Fazal: Thing is I'll have to do other calculations as well in other functions, but for this, it works fine. Thanks!
