Can someone explain me the first question of the Module 2 Quiz ?

Question

I don't understand the part with :
print(list[list[4]])

Why is there list twice ?

Answer 1

See if this makes sense to you:

list = [1, 2, 3, 4]
print( list[1] ) # this equals to 2

So,

list[ list[1] ] = list[2]

Answer 2

This example will help you:
You have an array (named "list") with these elements.
list[6]={1,2,3,4,5,0}. If you want to output list[list[4]] is the same like list[5]=0, because list[4]=5 (first index of array elements is 0). So just separate and calculate from inside...Hope you understood it...

Answer 3

Oh yes ! I understood !
Thank you so much ;)

Answer 4

I didn't understand the result one list was the call for the other. Now it's okay !
Thank you Ledio and Gustavo
