- The formatting operations described here are obsolete and may go away in future - versions of Python. Use the new :ref:
string-formattingin new code. + The formatting operations described here are modelled on C's printf() + syntax. They only support formatting of certain builtin types. The + use of a binary operator means that care may be needed in order to + format tuples and dictionaries correctly. As the new + :ref:string-formattingsyntax is more flexible and handles tuples and + dictionaries naturally, it is recommended for new code. However, there + are no current plans to deprecate printf-style formatting.
Please consider just deleting the last sentence. Documentation is meant for users (often new users) and not core devs. As such, I just don't see what it adds. If the aim to to document this intent somewhere, a PEP would be a better place than the formal documentation.
