list.without()?

Well...

def without( source, element):
	temp = source[:]
	while temp:
		try:
			temp.remove( element )
		except:
			break
	return temp

Seems to work.  I'm not sure if by "standard language" you were saying "in
the standard libraries", but there's certainly no non-standard Python in the
above.

Cheers,
Mike

Hi!

Is there a function or method in the standard language that can
non-destructively return a list without a specified element? Would it
be possible to add it as a method to lists?

i.e:

# pseudocode

class list:
    def without(self,element):
        temp = self[:]
        temp.remove(element)
        return temp

It might be useful - and sure beats using a temp-variable ;)
