Please help for Python programming

Actually, this script will open a text file which is seperated by tabs.


The PRINT code is for my testing. My problem is bytemsg will be omitted
some records. For example, my text file have 53 records about username.
After byteDict = users1[user1], it remains 50 records in the output
file.

I would like to know how to culmulate some data by users.

Thanks!
