At a Glance

iso8583 package supports custom specifications. See iso8583.specs module.

Use iso8583.decode() to decode raw iso8583 message.

>>> import iso8583
>>> from iso8583.specs import default_ascii as spec
>>> encoded_raw = b'02004000000000000000101234567890'
>>> decoded, encoded = iso8583.decode(encoded_raw, spec)

Use iso8583.encode() to encode updated ISO8583 message. It returns a raw ISO8583 message and a dictionary with encoded data.

>>> import iso8583
>>> from iso8583.specs import default_ascii as spec
>>> decoded = {"t": "0200", "2": "1234567890", "39": "00"}
>>> encoded_raw, encoded = iso8583.encode(decoded, spec)

To install:

pip install pyiso8583
