Thank you all for your suggestions.
I followed the following way
1.Define a class
2.In class overwrite __cmp__ function.
3.While reading file populate class object and append it in array.
4.Call array.sort() method. Internally it calls __cmp__ function.



Thanks,
Sheetal

1. Define a class to hold individual data

I want to sort this file on the basis of first field i.e. LogTime

Any pointers,how to do this?

Thanks in advance.



Thanks & Regards,

Why not use the csv module from the standard library? Should be simple
to read the lines in using the CSVReader and have it already split for
you. I'd recommend reading it into a dict and then sorting the dict
based on that field as was already mentioned.

Isn't the standard library csv module dependent on a C extension?

There are recipes here for reading a CSV with a .NET library and
IronPython:

Ah, could be, although I thought I had used it in IronPython before,
but I could be thinking of something else.
