Question

该程序正在读取附有数字值的关键字文件。然后它正在读取包含纬度和经度以及推文文本的几千条推文的文件。您必须将推文排序到特定区域，然后根据第一个文档的关键字和值计算每个区域的情绪平均值。用户必须将这些输入到两个文件中，并且必须有一个带有异常错误的try语句。这些函数可以单独计算正确的值，但是当我把它放在try语句中时，我会得到这些错误：

回溯（最近一次调用最后一次）：对于第129行main（）和第16行sortKets（键）。最后一个错误行56关键字[lines [0]] = int（lines [1]）IndexError：列表索引超出范围我能做些什么来解决它？

你有问题：

def sortKeys(keys): 
    for line in keys : 
        lines = line.split(",") 
        keyword[lines[0]] = int(lines[1])

当你分割线时，你不会得到2个令牌，只有一个。当您尝试拆分的行不包含“＆＃39;”时，会发生这种情况。字符。尝试使用python控制台中的某些内容＆＃34; xxxx＆＃34; .split（＆＃34;，＆＃34;），你会看到结果是[＆＃34; xxxx＆＃34;]，所以一个列表只是一个元素，而在您的代码行[1]尝试访问列表的第二个元素。

将读取用户输入文件的函数放入并使用异常循环
