Placing an element at the beginning of a list

Question

I have the below list:

list = ['A', 'B', 'C', 'D', 'E', 'F']

I'm trying to create a function that would place any of the elements at the beginning of it, for instance if I choose 'E', the list would end up:

newList = ['E', 'A', 'B', 'C', 'D', 'F']

How can I achieve this?

did you try anything at all? do you have sample code that will try to do it? — user3012759, Mar 10 '15 at 09:37

If it's a list you could use list.insert(0, 'E').

The aim is not to insert a element at the beginning of the list. The aim is to shift a element of the list to the beginning. – Thargor Mar 10 '15 at 09:47
I used list.pop(index('E')) and then list.insert(0, 'E') – Youri Nooijen Mar 10 '15 at 10:04

You can use a second list for that:

list = ['A', 'B', 'C', 'D', 'E', 'F']
new_list = ['E']
new_list.extend(list[:list.index('E')])
new_list.extend(list[list.index('E')+1:])
