This is called "percent formatting" or "printf-style formatting". It's
a means of formatting a tuple of values (or in this case, a single
value) into a string; the percent sign introduces a format string, and
the letter (in this case 'f') ends it, and says what kind of
formatting to use. Everything else is just part of the string.
>>> "Hello, %s!" % "world"
'Hello, world!'
>>> "%d + %d = %o... in octal! I'M FINE!" % (4, 4, 8)
"4 + 4 = 10... in octal! I'M FINE!"
As you can see, you can play with this at the interactive prompt to
find out what's happening.
