Question

我是Python编码的初学者。我正在编写这段代码，该代码应该让用户在几张表中看到世界人口信息，然后有几个选项只是具有最高，最低男女比例等的句子。

我遇到并修复了多个错误。我似乎无法修复的最后一个错误只是语法错误，但我无法弄清楚出了什么问题。它会弹出一个表示语法错误的框，并突出显示我的本地变量bothSexes_total。显示的选项打印一个表格。

def main():
    print("Welcome user.") #greetings
    Ages0_14= open("Ages0-14.txt", "r") #open files needed
    Ages15_64= open("Ages15-64.txt", "r")
    Ages65= open("Ages65.txt", "r")
    countries, males0_14, females0_14= get_lists(Ages0_14) #makes 3 lists from 1st file
    empty, males15_64, females15_64= get_lists(Ages15_64) #2 lists from 2nd file
    empty2, males65, females65= get_lists(Ages65) #2 lists from 3rd file
    print_menu()
    choice= input("Type the letter of the choice you would like to make.") #user makes choice

    if choice== "A" or choice== "a": #option a: display country's information
        country_input= input("Choose a country you would like to know the population information of.")
        country=(countries.index(country_input) #find index of country

        # I get an error here:
        bothSexes_total=(int(females0_14[country])+ int(females15_64[country])+ int(females65[country])+ int(males0_14[country])+ int(males15_64[country])+ int(males65[country]))
            male_total=(males0_14[country]+ males15_64[country]+ males65[country]) #male total from all ages
            female_total=(females0_14[country]+ females15_64[country]+ females65[country]) #female total from all ages

Answer 1

你忘了在前一行关闭你的父母。

Answer 2

请记住，在python中，每当它返回错误并突出显示某个特定的单词/短语时，错误很可能在突出显示之前。所以说我有：

name = input("enter your name"

print(name)

然后突出显示print，然后错误就是之前的错误，因为你可以看到我忘了关闭输入函数的括号。

希望这会有所帮助
