Graded Assignment 1, Question No. 20

[Arati Jose]

Hi 

The answer of this question which asked about the data type of the position of words in the  "Paragraph Words " dataset is given as integers.

But if we talk about the position of an element in any collection, it is written or said as "first, second, third etc" or "1st, 2nd, 3rd..." 

So shouldn't this be a string data type

Hi 

Please look into this question

Thank You

It's more predictable and much easier to work with numbers than strings, so numbers are preferred in most solutions.

That's the simplest answer.  If you want to go deeper, wait until you start working with strings...
