如何修复“Python Return Method”不返回串联字符串中的整数

Question

当代码运行时，它会输出，但不是按要求输出，它会在所有百分比上返回空白

def income():
    num= raw_input("Enter your Income: ")
    print "Your income is: %d " % int(num)
    return num
income= income()

def bills_expenses():
    bills_kitty=0
    bills_kitty=(income*(55/100))
    return  ("Your bills kitty should have: ", bills_kitty)

def long_term_savings():
    long_term_savings_kitty=(10/100)*income
    return "Your long term kitty should have: ",  long_term_savings_kitty

def play_and_leisure():
    play_and_leisure_kitty=(10/100)*income
    return "Your play and leisure kitty should have: " , play_and_leisure_kitty


def education_personal_growth():
    education_personal_growth_kitty=(10/100)*income
    return "Your personal growth  kitty should have: ", education_personal_growth_kitty


def pay_myself_Financial_fredom():
    pay_myself_Financial_fredom_kitty=(10/100)*income
    return "Your pay yourself kitty should have: ", pay_myself_Financial_fredom_kitty

def give_back_to_the_community():
    give_back_to_the_community_kitty=(5/100)*income
    return "Your giving back kitty should have: " , give_back_to_the_community_kitty



bills=bills_expenses()
long_term = long_term_savings()
play=play_and_leisure()
education=education_personal_growth()
mine=pay_myself_Financial_fredom()
give=give_back_to_the_community()


print bills
print long_term
print play
print education
print mine
print give

预期的结果是，调用每个方法时都应该输出百分比。 但这就是我得到的。你知道吗

Enter your Income: 200
Your income is: 200
('Your bills kitty should have: ', '')
('Your long term kitty should have: ', '')
('Your play and leisure kitty should have: ', '')
('Your personal growth  kitty should have: ', '')
('Your pay yourself kitty should have: ', '')
('Your giving back kitty should have: ', '')

我错过了什么？你知道吗

代码非常清楚：income返回一个字符串。您对字符串的“算术”返回一个空字符串。在返回之前将其转换为int。另外，不要重载变量income：

def get_income():
    num = int(raw_input("Enter your Income: "))
    print "Your income is: %d " % num
    return num

income = get_income()
