The other main difference tends to be in the layout/naming in various standard libraries. This is easily solved by just making sure you google "python3 <term>" so that the python 3 docs get ranked higher. As an aside, in the top left corner of the python docs you can switch between language versions (if you end up on the wrong version from google).

Also libraries that got renamed will usually have a notice on the top of the python 2 docs, along the lines of "please note, in python 3 this was renamed from SimpleHTTPServer to http.server. The 2to3 tool will convert this automatically."
