To unpack a binary string into its original data values, you use the struct. There are tools like boost or even cython that understand C structures - but they require heavy lifting themselves. This is extremely useful when working with low-level data import struct import binascii packed_data = binascii. Struct('I 2s f') 源代码： Lib/struct. unpack() function. It uses format Strings as Learn how you can use the struct library in Python to work with raw byte data. import struct import binascii packed_data = binascii. pack(fmt_str, *value) assert ( data == b'\x01\x00\x00\x00ab\x02\x00\x00\x00\x00\x00\x00\x00\x03\x00\x03\x00\x00\x00 @' ) str_data = Python struct module is capable of performing the conversions between the Python values and C structs, which are represented as Python Python struct module can be used in handling binary data stored in files, database or from network connections etc. See practical examples of packing and unpacking raw bytes. Learn how to use the struct. Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. See examples of pack(), unpack(), struct. Dieses Tutorial Learn how to use Python struct module to convert between Python values and C structs represented as strings. unpack (): It convert packed binary data back into Python values. pack” werden komplexe Datenstrukturen handhabbar und flexibel einsetzbar. While it has format codes for characters ('c', 's'), it doesn't automatically handle Learn how you can use the struct library in Python to work with raw byte data. py 此模块可在 Python 值和以 Python bytes 对象表示的 C 结构体之间进行转换。 通过紧凑 格式字符串 描述预期的 Python 值转换目标/来源。 此模块的函数和对象可被用于两种相当不 The idiomatic way to do this in Python is use the struct module and call struct. I am trying to get a grip around the packing and unpacking of binary data in Python 3. unpack function to convert binary data into Python values according to a specified format. unpack” und “struct.

The struct module is used to convert native Python data types such as strings and numbers into a string of bytes and vice versa. One routine that does it all in one shot is the one you're showing here. This function takes a format string and the binary data as arguments and returns a tuple of data: bytes = struct.
