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.
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.
The look-and-say sequence is a concealed and mysterious topic of mathematics. But don’t think of it as just a sequence. It’s more than a sequence. This sequence has a unique and mysterious characteristic that is really difficult to understand and solve.
Find the n’th term in Look-and-say (Or Count and Say) Sequence.
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...
The look and say sequence is a sequence of integerse that is defined from the previus sequence by noting how many times an integer is occuring in the prevoius sequence.
In mathematics, the look-and-say sequence is the sequence of integers beginning as follows

The following implementation of the look and say sequence leans on Python’s iterators and generators, and provides an incidental example of how to use Python’s doctest module. def look_and_say_numbers(): """ Generate the look-and-say number sequence.
There is no "base" involved in the look-and-say sequence. As defined, each term of the sequence is not an integer, but a finite sequence of integers.
