Please consider reading the subject of a message occasionally :) | >>> value = 3.141592654 | >>> print "%1.3f" % value | 3.142 | >>> print "%10.3f" % value | 3.142 | >>> print "%*.3f" % (1, value) | 3.142 | >>> print "%*.3f" % (10, value) | 3.142 | >>> for n in range(11): | ... print "%*.3f" % (n, value) | ... | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | 3.142 | >>> > > > there you go :) There *you* go :) > look at printf in c for general ideas about the format > specifiers Unfortunately this is about the same advice as given by the official Python tutorial: """Most formats work exactly as in C [snip] Using * to pass the width or precision in as a separate (integer) argument is supported""" Not quite so many folks come to Python with a background in C these days. Is anyone aware of a tutorial that covers % formatting from a standing start? Cheers, John -- http://mail.python.org/mailman/listinfo/python-list
