You have finished a lot of language tutorials. What's up with that? Shouldn't you know these things?

Arbitrary order means random order.

Do you mean arbitrary? It means that the elements of the array are not ordered by size or anything, but can have any order.

An array will not reorder the elements without you knowing. You can put them in an arbitrarily chosen spot, and then they will remain just there.

Let's say you have the numbers 1, 2, 3, 4, 5. An array doesn't mind in which order you store them. Could be... [1, 2, 3, 4, 5], [5, 4, 3, 2, 1], [2, 1, 4, 5, 3] ... or really any other imaginable order. What part of the tutorial are you referring to?

Keeping data in any order means not much but while using arrays for display you have to sort. In that case for example if you are using an array which you have to sort every time you display it would be good practice to sort it once and store it as sorted will reduce the cpu usage by not sorting it every time you use.

Suppose, if I access as index - 0 then, each time it will return different value ?

Arbitrary position is an index in array. Am I right ?

When you create your array it has its own index arrArray=['data1','data5','data3','data12] When you look at it you can say there is no order right?? Infact there is for the array When you print arrArray[0] which is first record in array will be 'data1' So arrArray[0] ==> data1 arrArray[1] ==> data5 arrArray[2] ==> data3 arrArray[3] ==> data12 Every time you use arrArray[2] you get data3 so arrays has their index but this order won't look nice we call this arbitrary, this order happens by creation. Yes you can create an array with ordered list but in any case array does not care what you stored in them and it will be arbitrary for it. We use dictionary instead of array which is still array at the end but with your own indexes. I hope this helps https://code.sololearn.com/Wxl8PLTurX7n/?ref=app https://code.sololearn.com/cBn14T9gv7gR/?ref=app
