The application for this is to save GPS trackpoints composed by (unix-timestamp, latitude, longitude, elevation), so the whole structure is little-endian "Long, float, float, float", with four bytes to each value. WebApr 7, 2024 · And that is true, a byte string is an array of 8 bits byte. There is not problems for bytes 0 to 127, but for example unsigned byte 255 and signed byte -1 have the exact same representation 0xFF in hexa. And there is no mean to guess whether that 0xFF is intended to be a 255 or a -1. signed_byte = signed.to_bytes (1, "little", signed=True ...

WebJun 17, 2014 · As you have a bytes string and you want to strip the right-most eight bits (i.e. one byte), you can simply it from the bytes string: >>> b'\x93\x4c\x00'[:-1] b'\x93L' If you want to convert that then to an integer, you can use Python’s struct to unpack it. As you correctly said, you need a fixed size to use structs, so you can just pad the bytes string …
WebApr 8, 2024 · Your bytes object is almost JSON, but it's using single quotes instead of double quotes, and it needs to be a string. So one way to fix it is to decode the bytes to str and replace the quotes. Another option is to use ast.literal_eval; see below for details.
