.. module:: stdnum
.. include:: ../README
:end-before: Available formats
Common Interface
----------------
Most of the number format modules implement the following functions:
.. function:: module.validate(number)
Validate the number and return a compact, consistent representation of
the number or code. If the validation fails,
:mod:`an exception <.exceptions>` is raised that indicates the type of
error.
.. function:: module.is_valid(number)
Return either ``True`` or ``False`` depending on whether the passed number
is in any supported and valid form and passes all embedded checks of the
number. This function should never raise an exception.
.. function:: module.compact(number)
Return a compact representation of the number or code. This function
generally does not do validation but may raise exceptions for wildly
invalid numbers.
.. function:: module.format(number)
Return a formatted version of the number in the preferred format.
This function generally expects to be passed a valid number or code and
may raise exceptions for invalid numbers.
The check digit modules generally also provide the following functions:
.. function:: module.checksum(number)
Calculate the checksum over the provided number. This is generally a
number that can be used to determine whether the provided number is
valid. It depends on the algorithm which checksum is considered valid.
.. function:: module.calc_check_digit(number)
Calculate the check digit that should be added to the number to make it
valid.
Apart from the above, the modules may add extra parsing, validation or
conversion functions.
Helper functions and modules
----------------------------
.. autosummary::
:toctree:
exceptions
.. autofunction:: get_cc_module
Searches the stdnum collection of modules for a number format for a
particular country. `name` may be an aliased name. For example:
>>> from stdnum import get_cc_module
>>> get_cc_module('nl', 'vat')
<module 'stdnum.nl.btw' from '...'>
Will return ``None`` if no module could be found. The generic names that
are currently in use:
* ``'vat'`` for value added tax numbers
* ``'businessid'`` for generic business identifiers (although some countries
may have multiple)
* ``'personalid'`` for generic personal identifiers (some countries may have
multiple, especially for tax purposes)
* ``'postcal_code'`` for address postal codes
