.. module:: stdnum
python-stdnum
=============
A Python module to parse, validate and reformat standard numbers and codes
in different formats. It contains a large collection of number formats.
Basically any number or code that has some validation mechanism available
or some common formatting is eligible for inclusion in this library.

Common Interface
----------------
Most of the number format modules implement the following functions:
.. function:: is_valid(number)
Returns 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.
.. function:: compact(number)
Returns a compact representation of the number or code. This function
generally does not do validation but may raise exceptions for wildly
invalid numbers.
.. function:: format(number)
Returns a formatted version of the number in the preferred format.
This function generally expects to be passed a valid number or code.
The check digit modules generally also provide the following functions:
.. function:: checksum(number)
Calculate the checksum over the provided number.
.. function:: 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.
