please help me out to resolve the issue, I'm not understanding how to use pyx12 parser library which is available in python or implement the code using pyx12
It looks like you've lost a bit of your formatting.
The ~ is the segment terminator.  The * character is the element separator.  So you should first split by the segment end, read each segment in, and then parse each element.
There is the concept of qualifiers, backed by a dictionary.  The N1 segment typically holds names, with N3 and N4 being address segments.  The first element in the N1 segment (N101) is a qualifier. It describes the data in the N102 using a code value.  The 834 has many of these.
REF170001~
REFDX0001~
In this case 17 and DX describe what value is in the REF02.
You should download a tool like EDI Notepad so that you can understand what each element is, what it means and how to parse it into something your application can understand.
