Feature request: New string conversion type to ignore list item

[thoma...@gmail.com]

Hi,
let's assume you want to nicely print the content of a list except for
one (or some)
individual item. You could do it like this:

t = ["foo", "skip me", 1, 2, 3]
print("text: %s\nvalues: %i %i %i" % (t[0], t[2], t[3], t[4]))

If there was a conversion type which simply ignores the corresponding
list item
- let's call it "%v" like "void" - things would be much easier:

t = ["foo", "skip me", 1, 2, 3]
print("text: %s\nvalues: %v%i %i %i" % t)

I guess that this new conversion type wouldn't break any existing
code.
What do you think?

Cheers,
Tom

or like this:

>>> "%s %.s %s" % ("first", "second", "third")
'first third'

Hey, that's great, thanks Peter!

Why not be consistent with other aspects of the language:

"%s %!s %s" % ("first", "second", "third")

You may be interested in the Python 3000 plans, where this is written::

'{0} {2}'.format('first', 'second', 'third')
