Can someone please help me understand this code

Question

fruits = [“apples”,”cherries”,”orange”,”banana”]

for fruits[-1] in fruits:
print(fruits[-1], end=“|”)

The output is apples|cherries|orange|orange

Can someone explain the step by step sequence of this code?

How is banana removed from the list?

Answer 1

on first iteration,
fruits[-1]="apples"

list looks like the following now,

["apples", "cherries", "or.. ", " apples"]
_________________________
On second iteration,
fruits[-1]="cherries"

List now looks like : ["apples", "cherries", "or.. ", " cherries"]
_________________________
On third iteration,
fruits[-1]="orange"

List now looks like : ["apples", "cherries", "or.. ", " orange"]
_________________________
On fourth iteration,
fruits[-1]="orange"

List now looks like : ["apples", "cherries", "or.. ", " orange"]

An explanation upon Abhay 's comment:
Consider this:
for x in fruits:
In each iteration, x is equal to one item of "fruits". When we replace x with fruits[-1] (the last item), that item value also is assigned to fruits[-1]. So in the third iteration, fruits[-1] will be equal to the third item. and so on...

This question was intetesting to me, so I searched a bit, and found this:
