BAI2Parser

✓ from bai2 import BAI2Parser

✗ from bai2 import BAI2Parser

Parse a BAI2 file string and access account and transaction data.

from bai2 import BAI2Parser parser = BAI2Parser() # Replace with actual BAI2 file content bai2_content = "01,MINISTRYOFJUSTICE,230421,123456,USD,001\n02,1234567890,USD,001\n03,1234567890,USD,001,220421,220421\n16,190,4,0001,4000000,,\n22,1,8,1000000,,\n49,10000000,4,,\n98,10000000,1,, 99,10000000,1,," result = parser.parse(bai2_content) print(result.number_of_accounts) print(result.accounts[0].transactions[0].amount)

Debug

Known issues

gotchaThe BAI2Parser.parse() method expects a string, not a file path. You must read the file yourself.

fix

Use open('file.bai2', 'r').read() to pass the content.

affects: all

gotchaThe library does not validate the BAI2 structure strictly. Malformed files may raise exceptions or produce incomplete objects.

fix

Always wrap parsing in try/except and check for None fields.

affects: all

deprecatedThe library's Python requirement is >=3.6, but some internal type hints may not be compatible with Python 3.6 edge cases.

fix

Use Python 3.7 or later if you encounter RuntimeError related to 'from __future__ import annotations'.

affects: 0.15.0
