In Python 2 a tab will be equal to eight spaces as indentation, so you can indent one line with a tab, and the next line with eight spaces. This is confusing if you are using an editor that expands tabs to another number than eight spaces.

In Python 3 a tab is only equal to another tab. This means that each indentation level has to be consistent in its use of tabs and spaces. If you have a file where an indented block sometimes uses spaces and sometimes tabs, you will get the error TabError: inconsistent use of tabs and spaces in indentation.

   Setuptools provides a facility to invoke 2to3 on the code as a part of the build process, by setting the keyword parameter use_2to3 to True, but the Setuptools project strongly recommends instead developing a unified codebase using six, future, or another compatibility library.
