In order to distinguish between, for example:
>>> '%c' % 42 '*' >>> '%d' % 42 '42' >>> '%e' % 42 '4.200000e+01' >>> '%f' % 42 '42.000000' >>> '%g' % 42 '42' >>> '%i' % 42 '42' >>> '%o' % 42 '52' >>> '%r' % 42 '42' >>> '%s' % 42 '42' >>> '%u' % 42 '42' >>> '%x' % 42 '2a' -- http://mail.python.org/mailman/listinfo/python-list
