struct
— manipulation of c-style data¶
This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: struct.
Supported size/byte order prefixes: @, <, >, !.
Supported format codes: b, B, x, h, H, i, I, l, L, q, Q, s, P, f, d (the latter 2 depending on the floating-point support).
-
struct.
calcsize
(fmt)¶ Return the number of bytes needed to store the given fmt.
-
struct.
pack
(fmt, *values)¶ Pack the values according to the format string fmt. The return value is a bytes object encoding the values.
-
struct.
pack_into
(fmt, buffer, offset, *values)¶ Pack the values according to the format string fmt into a buffer starting at offset. offset may be negative to count from the end of buffer.
-
struct.
unpack
(fmt, data)¶ Unpack from the data according to the format string fmt. The return value is a tuple of the unpacked values. The buffer size must match the size required by the format.
-
struct.
unpack_from
(fmt, data, offset=0)¶ Unpack from the data starting at offset according to the format string fmt. offset may be negative to count from the end of buffer. The return value is a tuple of the unpacked values. The buffer size must be at least as big as the size required by the form.
