Return a tuple containing values unpacked according to the format string S.format. The buffer's size in bytes, minus offset, must be at least S.size. See help(struct) for more on format strings.S.unpack(buffer) -> (v1, v2, ...)
Return a tuple containing values unpacked according to the format string S.format. The buffer's size in bytes must be S.size. See help(struct) for more on format strings.S.pack_into(buffer, offset, v1, v2, ...)
Pack the values v1, v2, ... according to the format string S.format and write the packed bytes into the writable buffer buf starting at offset. Note that the offset is a required argument. See help(struct) for more on format strings.S.pack(v1, v2, ...) -> bytes
Return a bytes object containing values v1, v2, ... packed according to the format string S.format. See help(struct) for more on format strings.S.iter_unpack(buffer) -> iterator(v1, v2, ...)
Return an iterator yielding tuples unpacked from the given bytes source, like a repeated invocation of unpack_from(). Requires that the bytes length be a multiple of the struct size.Struct(fmt) --> compiled struct object
Return a new Struct object which writes and reads binary data according to the format string fmt. See help(struct) for more on format strings.unpack_from(fmt, buffer, offset=0) -> (v1, v2, ...)
Return a tuple containing values unpacked according to the format string fmt. The buffer's size, minus offset, must be at least calcsize(fmt). See help(struct) for more on format strings.unpack(fmt, buffer) -> (v1, v2, ...)
Return a tuple containing values unpacked according to the format string fmt. The buffer's size in bytes must be calcsize(fmt). See help(struct) for more on format strings.pack_into(fmt, buffer, offset, v1, v2, ...)
Pack the values v1, v2, ... according to the format string fmt and write the packed bytes into the writable buffer buf starting at offset. Note that the offset is a required argument. See help(struct) for more on format strings.pack(fmt, v1, v2, ...) -> bytes
Return a bytes object containing the values v1, v2, ... packed according to the format string fmt. See help(struct) for more on format strings.iter_unpack(fmt, buffer) -> iterator(v1, v2, ...)
Return an iterator yielding tuples unpacked from the given bytes source according to the format string, like a repeated invocation of unpack_from(). Requires that the bytes length be a multiple of the format struct size.calcsize(fmt) -> integer
Return size in bytes of the struct described by the format string fmt.Clear the internal cache.Functions to convert between Python values and C structs. Python bytes objects are used to hold the data representing the C struct and also as format strings (explained below) to describe the layout of data in the C struct.
The optional first format char indicates byte order, size and alignment: @: native order, size & alignment (default) =: native order, std. size & alignment <: little-endian, std. size & alignment >: big-endian, std. size & alignment !: same as >
The remaining chars indicate types of args and must match exactly; these can be preceded by a decimal repeat count: x: pad byte (no data); c:char; b:signed byte; B:unsigned byte; ?: _Bool (requires C99; if not available, char is used instead) h:short; H:unsigned short; i:int; I:unsigned int; l:long; L:unsigned long; f:float; d:double; e:half-float. Special cases (preceding decimal count indicates length): s:string (array of char); p: pascal string (with count byte). Special cases (only available in native format): n:ssize_t; N:size_t; P:an integer type that is wide enough to hold a pointer. Special case (not in native mode unless 'long long' in platform C): q:long long; Q:unsigned long long Whitespace between formats is ignored.
