What does the ‘b’ character do in front of a string literal?

To quote the Python 2.x documentation: A prefix of ‘b’ or ‘B’ is ignored in Python 2; it indicates that the literal should become a bytes literal in Python 3 (e.g. when code is automatically converted with 2to3). A ‘u’ or ‘b’ prefix may be followed by an ‘r’ prefix. The Python 3 documentation states: Bytes literals are … Read more

Reading a binary file with python

Read the binary file content like this: then “unpack” binary data using struct.unpack: The start bytes: struct.unpack(“iiiii”, fileContent[:20]) The body: ignore the heading bytes and the trailing byte (= 24); The remaining part forms the body, to know the number of bytes in the body do an integer division by 4; The obtained quotient is multiplied by … Read more
