语法错误 - 突出显示一个变量Python

问题描述：

我是Python编程的初学者。我正在编写这样的代码，它应该让用户在几张表格中看到世界上的人口信息，然后有几个选项只是最高和最低男女比例的句子等。语法错误 - 突出显示一个变量Python

我有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，但我无法弄清楚什么是错误的。它会弹出一个说明语法错误的框，并突出显示我的本地变量bothSexes_total。显示的选项打印一张表格。

    print("Welcome user.") #greetings

你忘了在上一行关闭你的parens。

更具体地说，'国家=（countries.index（country_input）'有2个开放的括号和一个密切括号。 – Amber 2014-12-07 21:01:00

请记住，在Python中，只要它返回一个错误并突出显示一个特定的单词/短语，就很可能错误在突出显示之前。所以说，我有：

name = input("enter your name" 

print(name)

和print被突出显示，则错误是什么之前，正如你可以看到我忘了关括号内为输入功能。

希望这有助于
