Despite being a day-to-day python programmer (scientific computing with some django on the side), apparently I've been living under a rock. When did .format supersede normal printf-style string formatting, ie. "%f" % (3.14)? Is the latter now deprecated?
- jspiral 14y agoHints have appeared suggesting that interpolation will be deprecated at some point in python 3, e.g. from this article: http://docs.python.org/dev/py3k/whatsnew/3.0.html#changes-already-present-in-python-2-6 http://docs.python.org/dev/py3k/whatsnew/3.0.html#changes-al... PEP 3101: Advanced String Formatting. [...] The plan is to eventually make this the only API for string formatting, and to start deprecating the % operator in Python 3.1. As far as I know, interpolation is not actually deprecated yet though.

Not at all, and not expected to be, though str.format is recommended going forward: http://docs.python.org/py3k/library/stdtypes.html#old-string-formatting-operations http://docs.python.org/py3k/library/stdtypes.html#old-string... > As the new String Formatting syntax 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.
