It doesn’t tell you enough about how to convert text to binary data and vice versa. While the “underlying number” is the same, all numbering systems are just different ways of expressing the same number.However, this string representation can express different underlying numbers in different numbering systems. You ASCII’s underutilization of the 8-bit bytes offered by modern computers led to a family of conflicting, informalized encodings that each specified additional characters to be used with the remaining 128 available code points allowed in an 8-bit character encoding scheme.Not only did these different encodings clash with each other, but each one of them was by itself still a grossly incomplete representation of the world’s characters, regardless of the fact that they made use of one additional bit. I already tried importing the 'encodings' module in my testscript but it is still not working, I have also tried py2exe and it is also not working at all.Is there anything I do wrong? yourself: open a file, read an 8-bit bytes object from it, and convert the bytes characters. code points.
