This file contains more detailed doctests for the stdnum.cfi module. It
tries to validate a number of numbers that have been found online.
>>> import json
>>> from stdnum import cfi
>>> from stdnum.exceptions import *
Check some obviously invalid numbers.
>>> cfi.validate('123456')
Traceback (most recent call last):
...
InvalidFormat: ...
>>> cfi.validate('ELNUF')
Traceback (most recent call last):
...
InvalidLength: ...
>>> cfi.validate('AAAAAA')
Traceback (most recent call last):
...
InvalidComponent: ...
>>> cfi.validate('XXAAAA')
Traceback (most recent call last):
...
InvalidComponent: ...
>>> cfi.validate('IFXXXZ')
Traceback (most recent call last):
...
InvalidComponent: ...
Most characters can be replaced by an X.
>>> cfi.validate('DTFNFR')
'DTFNFR'
>>> cfi.validate('DTXXXX')
'DTXXXX'
>>> cfi.validate('DTFNXX')
'DTFNXX'
>>> cfi.validate('DTXNFX')
'DTXNFX'
The info function returns useful information.
>>> print(json.dumps(cfi.info('DTFNFR'), indent=2, sort_keys=True))
{
"Form": "Registered",
"Guarantee or ranking": "Senior",
"Redemption/reimbursement": "Fixed maturity",
"Type of interest": "Fixed rate",
"category": "Debt instruments",
"group": "Medium-term notes"
}
>>> print(json.dumps(cfi.info('IFXXXP'), indent=2, sort_keys=True))
{
"Delivery": "Physical",
"category": "Spot",
"group": "Foreign exchange"
}
>>> print(json.dumps(cfi.info('IFXXXX'), indent=2, sort_keys=True))
{
"category": "Spot",
"group": "Foreign exchange"
}
>>> print(json.dumps(cfi.info('DBFNXR'), indent=2, sort_keys=True))
{
"Form": "Registered",
"Guarantee or ranking": "Senior",
"Type of interest or cash payment": "Fixed rate",
"category": "Debt instruments",
"group": "Bonds"
}
These should all be valid numbers.
