[$] Easier Python string formatting
Some languages pride themselves on providing many ways to accomplish any
given task. Python, instead, tends to focus on providing a single solution
to most problems. There are exceptions, though; the creation of formatted
strings would appear to be one of them. Despite the fact that there are
(at least) three mechanisms available now, Python's developers have just
adopted a plan to add a fourth.
With luck, this new formatting mechanism (slated for Python 3.6) will
improve the traditionally cumbersome string-formatting facilities available
in Python.
