Terry J. Reedy added the comment: IndexError should be caught and replaced with something like ValueError('format string requests argument not passed') or TypeError('arguments do not match format string') or more specific TypeError('format string requests at least %d positional arguments, only %d passed') In Roy's example (a good testcase), the numbers would be 1 and 0.
