Python 2.7無效的語法錯誤

Question

我是一名初學者學習Python，我運行了類似於這段代碼的東西，它工作正常。然後我做了一些改變（比如不是隻有一個乘法函數，而是創建了multiply_two和multiply_three函數）並再次運行它，但是我總是在total_hours_worked = float（...）和其他兩個正確的位置我想不出我做錯任何意見讚賞

def multiply_two(a, b): 
    print "Multiplying %d and %d to get annual earnings." % (a, b) 
    return a * b 

def multiply_three(a, b, c): 
    print "Multiplying %d, %d, and %d to get total hours worked per year." % (a, b, c) 
    return a * b * c 

def add(a, b): 
    print "Adding %d and %d to get total annual compensation." % (a, b) 
    return a + b 

hours_worked = float(raw_input("How many hours per day do you work?\n> ")) 
days_worked = float(raw_input("How many days per week do you work?\n> ")) 
weeks_worked = float(raw_input("How many weeks per year do you work?\n> ")) 
wage = float(raw_input("What is your hourly wage?\n> ")) 
bonus = float(raw_input("What is your yearly bonus amount, in dollars?\n ") 

total_hours_worked = float(multiply_three(hours_worked, days_worked, weeks_worked)) 
annual_earnings = float(multiply_two(total_hours_worked, wage)) 
total_annual_compensation = float(add(annual_earnings, bonus)) 

print "\nYour total hours worked per year are %r." % total_hours_worked 
print "Your annual earnings are $%r." % annual_earnings 
print "Your total annual compensation is $%r." % total_annual_compensation 

Answer 1

你錯過了一個括號「）」在行的末尾：。

 
bonus = float(raw_input("What is your yearly bonus amount, in dollars?\n ")
