@ -257,10 +257,11 @@ not contain whitespace though.
For the ``'s'`` format character, the count is interpreted as the size of the
string, not a repeat count like for the other format characters; for example,
``'10s'`` means a single 10-byte string, while ``'10c'`` means 10 characters.
For packing, the string is truncated or padded with null bytes as appropriate to
make it fit. For unpacking, the resulting string always has exactly the
specified number of bytes. As a special case, ``'0s'`` means a single, empty
string (while ``'0c'`` means 0 characters).
If a count is not given, it defaults to 1. For packing, the string is
truncated or padded with null bytes as appropriate to make it fit. For
unpacking, the resulting string always has exactly the specified number of
bytes. As a special case, ``'0s'`` means a single, empty string (while
``'0c'`` means 0 characters).
The ``'p'`` format character encodes a "Pascal string", meaning a short
variable-length string stored in a *fixed number of bytes*, given by the count.
