I have a list of tuples, and usually print them using: print c, " ".join(map(str, list_of_tuples))
This is beginning to feel clunky (but gives me essentially what I want), and I thought there was a better, more concise, way to achieve this, so I explored the new string format and format() function: >>> c = (1,3) >>> s = "{0[0]}" >>> print s.format(c) '1' >>> print format(c,s) Traceback (most recent call last): File "<interactive input>", line 1, in <module> ValueError: Invalid conversion specification I'm running *** Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32. *** (This is actually a PortablePython run on a Windows 7 machine) Any idea why one form works and the other doesn't? -- http://mail.python.org/mailman/listinfo/python-list
