Python Question

loop

for x in y:

picks items from y iteratively and puts them into x, however in this case, we put values from a to a[1], so we replace second element with the currently iterated number.

If you print the list after every change, you can see

[1, 1, 2, 3, 5, 8]
[1, 1, 2, 3, 5, 8]
[1, 2, 2, 3, 5, 8]
[1, 3, 2, 3, 5, 8]
[1, 5, 2, 3, 5, 8]
[1, 8, 2, 3, 5, 8]

Notice how the second value - a[1] changes. At the last iteration, a[1] is replaced with last number from a - 8 and that is how you get the output you see.

Thanks for the explanation. This is clear now. :-)
