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...

python look-and-say sequence improved - Stack Overflow


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.
