Python way of printing: with 'format' or percent form? [duplicate]
Use the format method, especially if you're concerned about Python 3 and the future. From the documentation:
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 deprecateprintf-style formatting.
