def sum（num1，num2）上的Python語法錯誤

Question

我在一個初學者編程類中，我應該讓這段代碼工作，我已經按照書的內容一遍又一遍地輸入它， m得到一個無效的語法錯誤，並在Python空閒是高清def總和（num1，num2） 我已經看遍了，在書中，在線，還沒有找到答案，爲什麼它給了我一個錯誤。

#this program uses the return value of a function 

def main(): 
    #Get the user's age 
    first_age = int(input('Enter your age: ')) 

    #Get the user's best friend's age. 
    second_age = int(input("Enter your best friend's age: ")) 

    #Get the sum of both ages 
    total = sum(first_age, second_age) 

    #Display the total age 
    print('Together you are', total, 'years old.') 

#the sum function accepts two numeric arguments and 
# return the sum of those arguments. 
def sum(num1, num2): 
    result = num1 + num2 
    return result 

#Call the main function 

main() 

SyntaxError: invalid syntax

您的代碼正在運行。你有像下面那樣的縮進嗎？我必須修復它才能使它工作。

def main(): 
    #Get the user's age 
    first_age = int(input('Enter your age: ')) 

    #Get the user's best friend's age. 
    second_age = int(input("Enter your best friend's age: ")) 

    #Get the sum of both ages 
    total = sum(first_age, second_age) 

    #Display the total age 
    print('Together you are', total, 'years old.') 

#the sum function accepts two numeric arguments and 
# return the sum of those arguments. 
def sum(num1, num2): 
    result = num1 + num2 
    return result 

#Call the main function 

main()
