I have a MARC21 record in an input file. I am trying to print it in Aleph Sequential format.

How?
I want to print record number (9 digits), space, the field tag, indicators, space, the L letter, space and then each subfield tag and subfield contests.

I am trying to use the record.get_fields(), but I do not succeed in getting the field indicators and subfield tag.

How cat I get and print field indicators? How do I print ech subfield tag and then each subfield value?

Here is my code:

from pymarc import MARCReader
from pymarc import Record, Field 

with open('machiavellism_biu_2018.mrc', 'rb') as fh:
    reader = MARCReader(fh, to_unicode=True) 
    # loop 1
    recnum = 0
    for record in reader: 
        # loop 2
        recnum += 1
        for tield_contents in record.get_fields():
            print ('%09d' % recnum,' ',tield_contents.tag,'  ',' L',tield_contents.value())
        ## end loop 2

An example for the output:

python pymarc_000002.py
