It would be prudent to note at this point that the term individual which is simply just a one-dimensional list, or array of values will be used interchangeably with the term vector, since they are essentially the same exact thing. In most cases the user does not need to have those objects remained in the diff unless for investigation purposes. It is a well-designed, modern programming language that is simultaneously easy to learn and very powerful. In Python, like in all programming languages, data types are used to classify one particular type of data. hm = diff_halfMatch(text1, text2) if hm: # A half-match was found, sort out the return data.
