>>>var=7 >>>array = [1,2,3,4,5,6] >>>array.insert(0,var) >>>array [7, 1, 2, 3, 4, 5, 6]
How it works:
array.insert(index, value)
Insert an item at a given position. The first argument is the index of the element before which to insert, so array.insert(0, x)
inserts at the front of the list, and array.insert(len(array), x)
is equivalent to array.append(x)
.Negative values are treated as being relative to the end of the array.
