Multiplying number in a list in an order

[DeaD_EyE]

It's important to understand the slicing syntax.
You can slice lists.

a_list = [0, 1, 2, 3, 4, 5]

left_side = a_list[1:] # [1, 2, 3, 4, 5]
right_side = a_list[:1] # [0]
# left side is from the index 1 to the end
# right side is from start to index 1

rolled_new_list = left_side + right_side # [1, 2, 3, 4, 5, 0]
# + operation on two lists will return a new chained list.

I still hope that someone is coming up with an itertools solution.
