Increment slice object?

Question

Is it possible to change the values in a python slice object?

For example, if I have

slice(0,1,None)

How would I, in effect, add 1 to the start and end values and so convert this to:

slice(1,2,None)

Answer 1

Not exactly elegant, but it works:

>>> s1 = slice(0,1,None)
>>> s2 = slice(s1.start + 1, s1.stop + 1, s1.step)
>>> s2
slice(1, 2, None)
>>>
