 Availability of codec for decoding CCSID 01153?

Does anyone know if there is codec available in z/OS Python 3.13/3.14 supporting  EBCDIC files encoded in CCSID 1153 (East European Latin2 EBCDIC w/Euro sign)? 

This code does not work:

with open(ebcdic_file, mode='r', encoding='cp1153') as source:
    content = source.read()

and fails:

LookupError: unknown encoding: cp1153

Using encoding=cp1047 works, but of course produces garbage with 1153 encoded EBCDIC data...

Should I write own codec? Is there one being used somewhere else?

Thanks for any hints and advice.

Hey Milan,

I'm not aware of any package that currently provides the IBM1153 codec - but there is a package available on PyPI and though the IBM Python AI Toolkit called ebcdic, which generates & adds a large number of EBCDIC codecs to Python. You may be able to modify and submit a pull request for IBM1153 to get access to it.

As a quick solution I built my own cp1153 codec - https://pypi.org/project/ccsid1153-codec/. Perhaps it helps others. Cheers!
