A lot of the breakage centers around strings. There’s a fairly steep learning curve, since you need to kind of understand the library first, so you can understand why it broke and how I fixed it. ( print is now a function, `x` doesn’t work, &c.)Ĭase Study: Porting chardet to Python 3 documents my (ultimately successful) effort to port a non-trivial library from Python 2 to Python 3. Since a lot of those things are syntax changes, it’s a good starting point to learn about a lot of the syntax changes in Python 3. Porting Code to Python 3 with 2to3 is a reference of all the things that the 2to3 tool can fix automatically. Python 3 comes with a script called 2to3. (If none of that is true, you’d be better off starting at the beginning.)
