将字符串解析为具有两个键和一个值的字典

Question

我有一个Python程序prog1 (映射器)在下面的三个字段中打印出来。它的结尾是

 print user, text, rt

第一个字段是用户名。其次是tweet text。第三个是转发数量。尝试找出TopN转发消息

下面是一个例子

我通过标准输入将其导入到另一个Python程序prog2 (reducer)中。我的问题是如何用两个键(user和text)和值(retweet)将其读入字典。

如果我说

for line in sys.stdin

line没有捕获整个字符串。我需要做的是用两个键和一个值捕获字典中的三个字段。

你能给我一些建议吗？我刚刚开始学习Python

谢谢
