Can someoneone explain what is going on in the >>>print (things[2][2])? Why does it output 3?

Question

number = 3
things = ["string", 0, [1, 2, number], 4.56]
print(things[2][2])

Answer 1

number = 3. number in the array at index [2] [2] is number which value is assigned as 3. The array things= ["string",0,[1,2,number], 4.56] things = ["string", 0, [1,2,3], 4.56]
I hope this helps.

Answer 2

print [2][2] the first [2] refers to:(1,2,number) the second [2] refers to number

Answer 3

number is a variable which was assigned the value 3 at the beginning of the code. In list thing there's another list. The first number 2 refer to the position of the list nested in list thing. the second number 2 is the index of variable number which value is 3. Hope this will be helpful.

Answer 4

In python when you write [ ][ ] it means you are getting into a list within a list.

In your case 1st [ ] represents list of things and 2nd [ ] represents list of [1,2,number].

Another things is that count of list is starts with 0 and then 1 and then 2 and so on.

So in things[2][2] means 1st [2] is position in list things which is [1,2,3] and 2nd [2] means 2nd position of this list which is 3.

Answer 5

It's point 2 of the original list (which is a nested list) and then point 2 of the nested list. I think...

Answer 6

It means "print the second number of the second list"

Answer 7

Remember that arrays always starts counting from 0 :)

Answer 8

1) In things array, index[ 3 ]refers to [1,2,number]
2) In that array inner index [3] refers to number,which already assigned to 3.😀....so output =3.

Answer 11

I think it basically means the 3rd [2] item in the list within the list (which is again the third [2] in the outer list). Hope that makes sense.
