Look-and-say sequence - Rosetta Code


The Look and say sequence is a recursively defined sequence of numbers studied most notably by John Conway. Sequence Definition. Take a decimal number. Look at the number, visually grouping consecutive runs of the same digit.

Look-and-say sequence - Wikipedia, the free encyclopedia


In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, ... (sequence A005150 in OEIS). To generate a member of the sequence from the previous member, read off the digits of the previous member...

Replace a[i] by last here (you may not want to add anything in the first round). After the loop you have to add the last value of the counter together with the last character again (this was not yet done), i.e. add another result = result+str(k)+last after the loop. In total it looks like.
