【问题标题】：Syntax Error- Highlights a variable Python [closed]语法错误 - 突出显示变量 Python [关闭]

【问题描述】：

我是 Python 编码的初学者。我正在编写这段代码，应该让用户在几个表格中看到世界人口信息，然后几个选项只是男女比例最高和最低的句子，等等。

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一个语法错误，但我不知道出了什么问题。它会弹出一个框，显示语法错误并突出显示我的局部变量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

标签： python variables syntax

【解决方案1】：

您忘记关闭上一行的括号。

【讨论】：

更具体地说，country=(countries.index(country_input) 有 2 个开括号和一个闭括号。

【解决方案2】：

请记住，在 python 中，每当它返回错误并突出显示特定的单词/短语时，错误很可能出现在突出显示的内容之前。所以说我有：

name = input("enter your name"

print(name)

print 被突出显示然后错误是之前的错误，如您所见，我忘记关闭输入函数的括号。

希望对你有帮助
