structs represented as Python strings. It uses \dfn{format strings}

The module defines the following exception and functions:

Format characters have the following meaning; the conversion between

\begin{tableiii}{c|l|l}{samp}{Format}{C Type}{Python}

\lineiii{x}{pad byte}{no value}

meaning a Python long integer will be used to hold the pointer; other

platforms use 32-bit pointers and will use a Python integer.

and byte order, and properly aligned by skipping pad bytes if

Alternatively, the first character of the format string can be used to

indicate the byte order, size and alignment of the packed data,

host system (e.g. Motorola and Sun are big-endian; Intel and DEC are

little-endian).

order.

standard size and alignment does not enforce any alignment.
