How can I use python for file processing

[yinglcs at gmail.com]

Hi,

I am trying to use python for file processing.
Suppose I have a file like this:
I want to build a Hashmap between the line "begin_QOS_statistics" and
"end_QOS_statistics"
and for each line I want to put the first text as the key of the hash
table and the second text as the value.
