Shifting the elements of a list

Question

L=["apple","banana","mango","kiwi"]

If the user enters a fruit, let's say banana, the output must be

["banana","mango","kiwi","apple"]

Should I use the back shifting principle? Please help.

Try [`rotate`](https://stackoverflow.com/questions/9457832/python-list-rotation) — Arunesh Singh, Nov 01 '17 at 10:41
I want the fruit that is entered by the user to be the first element — Supratha Thinakaran, Nov 01 '17 at 10:42
With `L.index(e)` your are getting the position of the element `e` in your list. `L.index("banana")` gives you `1`. — AnnetteC, Nov 01 '17 at 10:45
You can use: `fruit = 'banana'; L[L.index(fruit):] + L[:L.index(fruit)]` — ettanany, Nov 01 '17 at 10:52

You can try this:

from collections import deque
d = deque(["apple","banana","mango","kiwi"])
d.rotate(-list(d).index("banana"))
print(list(d))

Output:

['banana', 'mango', 'kiwi', 'apple']
