list() Ans- Create an empty list var = [ 0, 1, 2 ] Ans- Create a list and initialize it with the supplied values list()[start:end:step] Ans- Slice the list and return a copy. 'start' is the first index to return in the result. 'end' is the last index to return in the result. 'step' indicates which values to pull into the sublist. A 'step' of 1 returns every element, 'step' of 2 every other element, 'step' of 3 is every third element and so on. alist = [ 0, 1, 2, 3, 4, 5 ] ...
