Running 2to3

-

We’re going to migrate the chardet module from Python 2 to Python 3. Python 3 comes with a utility script called 2to3, which takes your actual Python 2 source code as input and auto-converts as much as it can to Python 3. In some cases this is easy — a function was renamed or moved to a different modules — but in other cases it can get pretty complex. To get a sense of all that it can do, refer to the appendix, Porting code to Python 3 with 2to3. In this chapter, we’ll start by running 2to3 on the chardet package, but as you’ll see, there will still be a lot of work to do after the automated tools have performed their magic. +

The main chardet package is split across several different files, all in the same directory. The 2to3 script makes it easy to convert multiple files at once: just pass a directory as a command line argument, and 2to3 will convert each of the files in turn.

A POST request is different from a GET request, because it includes a payload. The payload is the data you want to send to the server.
